Old picture but this is still what I'm running. 10 Compacs on a single 10 port A-300 hub I believe it's a relabeled https://www.amazon.com/Sipolar-USB2-0-Bitcoin-Indicator-Powered/dp/B01K4LYX7U/ref=sr_1_1?ie=UTF8&qid=1486327095&sr=8-1&keywords=sipolar+A-300

I heard those hubs broke pretty easily some time ago (don't remember when or where I heard that). Good to know that someone on the forum runs one of these hubs, once I get a few 2pacs and bit fury sticks I might consider this or the superbpag. Voltage is a little low on each port (5v600ma) compared to the superbpag but otherwise good; these also sell on eBay.

I can't even remember when U2s were still available, I started mining actively back when the U3 was still on sale and when you could easily get a Block Erupter for five bucks and shipping. Those were the old days.. Looks like a nice hub, illl consider it once I get my sticks Smiley

No pics at the moment, but I currently have this Anker USB 3.0 hub:
https://www.amazon.com/gp/product/B00EYXZI4M/

Works fine, but won't work with RPi, I would like to switch over to a different hub that I can run on the RPi. I currently have four compacs running at 275mhz and I have two 2Pacs ordered.

I was thinking of getting this:
https://www.amazon.com/Superbpag-Portable-Charger-Transfer-Samsung/dp/B013OK10YM

Hoping to find something to work with the RPi and be able to provide enough power for the 4 compacs and 2 2Pacs. Hoping to crank these things up 300+mhz.

You should be able to. Superbpaq supplies 2A for each port and works well with RPi.
You can push an original compac to somewhere around 340Mhz under 1.95A.

somehow, I was not able to run more than five overclocked Compacs on one Superbpag, but I did not try too hard.

For biggie(s) I am planning to use 300W PSU from my old HP500 tower that i upgraded to 500W.
It got PCie and biggie will get at least one PCIe connector. Should be easy peasy, I hope.
they sell on ebay for $25-28, great value, IMHO

Put the USB 3.0 hub into a non powered usb 2.0 hub. That is how I go my Orico A3H10 BK to work. Could not plug it into my powered Orico USB P10-U2-PK

Has anyone managed to modify an existing powered hub so it can support more power?

Has anyone managed to modify an existing powered hub so it can support more power?

I know I saw one picture of a Hub that had been opened up, and and additional +5V and GND wire had been soldered on top of the thin trace already present on the PC board. The idea is that the thin trace would have too much resistance and would cause a larger voltage drop when more current is drawn.

There were a lot of posts on this in the latter half of 2013 and early 2014 when USB miners were popular.

I think thats what ive already seen. It was to a standard hub which had the unsusd +5v and GND. Just wondering if you could modifiy an existing powered hub to "beef it up" powerwise. Where woild the most likely bottlenecks be to stop it drawing the maximum current possible?

My attempt at upping the power to my soon to be arriving 2pacs on the cheap. I'm reusing stuff I already had on hand.  I am waiting on my Block Erupters to sell on eBay to reclaim a 5v 40 amp led "meanwell" power supply. My plan is to use Monoprice usb extenders and some 18GA wire to hook up the power of the meanwell and data of a cheap 10 port hub (also hooked up to the meanwell) I hope to get these guys running at 3 to 3.5 amps per.

I slice the jacket and remove the red and black wire (verifying that they are the +5 and ground on the usb ports) Cut the red wire and cap the side coming from the usb hub. Solder in the new 18GA wire +5 and ground cables. Verify no shorts and wrap the solder joints on opposite sides of the usb cable.





I cut some 3/4 wood dowel and using a saw and 1/2 drill bit made usb "Holders" they are spaced 2" apart to allow cooling.
I plan on attaching these to the board that my power supply is mounted to and using hot glue attaching the usb "holders" to the wood dowel.
And then attaching cooling fans.
Will Post more pictures when I get it completed. Just wanted to throw this out in case it helps others.

What gauge are those USB wires?
I know it is a short distance, but will they carry the 3.5 amps without getting too hot?
I would guess they are only 28awg or 24awg.

I started looking for some cables to do this with and the biggest wire I can find is 22awg:
https://www.amazon.com/Sabrent-22AWG-Extension-Cable-Female/dp/B017XVCK7O

Thinking about just getting some of these:
https://www.amazon.com/Uxcell-Female-Socket-Connector-Pieces/dp/B00H51E7B0/
and making my own wires/hub assembly.

They were the "gold" series of usb extenders. 24GA if i can remember. They don't have them on the site anymore. I am pretty sure they are under rated for the job at hand. but I'm going try my luck. Like you said it's a short run and my worry is more of the usb connector than the wiring. I thought about building my own connections but couldn't work out something robust enough. I may have to if these fry. Cheesy

Yeah, I think I am going to try to keep things less than 3 amps. I don't think the little extra hashrate will make up for the additional cost to construct something that can handle more than 3 amps.

Keep us updated. Hoping to get my 2Pacs by the end of the week.  Cool

Ya I'm going to start off at 1.5 amp and work up slowly. Even if its 2 or 2.5 amps I'll be happy. I was trying not to fry the usb hub with 10 2pacs mainly. And ya I don't know where I am on the list but the wait is killing me lol

Same, I bought my stick pretty early but I'm not sure if it's shipped or not. Either way we're pretty much guaranteed a stick and I'll finally be able to test out my new hub. I'm more excited for the BF16 stick and overclocking that but we've got the 2pac for now.

Eeep. If shipping has started then I gotta get another Plugable hub from Amazon. https://www.amazon.com/gp/product/B00L2LK164/ref=od_aui_detailpages00?ie=UTF8&psc=1

Shoulda thought of that last night when I ordered two 5V wall warts and cables to feed the RasPi's for Avalon's I've picked up...  Roll Eyes

Leo, your sticks shipped yesterday. btckess is in the next batch of small orders.
Thanks for letting me know, I can hardly sleep without knowing when my stick shipped Smiley I will definitely let you guys know when I get mine and do some basic overclocking on my motherboard USB 3.0 port.

Leo, your sticks shipped yesterday. btckess is in the next batch of small orders.

This is great news, thanks for the update. I just got everything mounted and tested. Everything works great just need my 2pacs Cheesy
I think it turned out pretty good. The power supply was a little smaller than I thought, 30amps so I'm gonna try to run these guys at 2.2-2.4 amps. Very excited now!!  Grin

total cost around 5 bucks for some double sided tape plus stuff i had laying around.

Nice looking setup.

I got my 2Pacs plugged in and running, but not very fast right now, I need more power!
I'll get to it soon, hopefully this weekend.

Damn that's a serious cooling setup... wonder how high you'll be able to clock those sticks like that! Also bought one of your block erupters on eBay for my collection, works nice and well, I'll keep it in my drawer until I can get something to display it.

I had/have a bunch of hard drive coolers, like 100+ i got for a great deal .50 each.  These things are unstoppable. The asic that you bought was run by the power supply,raspberry pi, usb hub, and 3 of those 4 fans non-stop for 2 years with zero issues. Which is why I'm using the same setup with the 2pacs. Hopefully the usb extenders will hold up.

And as far as overclocking ... I hope i can get approx. 300gh out of this guy and have it stay nice and cool  Grin

That is a very nice looking setup you put together there - I hope everything works out after all that work (referencing your concern regarding sending that much current through wire of that gauge)! It looks sound & my bet would be that it will work fine with the 2PAC's! Keep us posted!!

I値l post an update when I get my 2pacs, no doubt. I think I値l be fine with the setup. I知 dropping the power from what I originally thought I was going to do.  And since this is a hobby and I知 not in this for a profit. I don稚 mind revising my creations. I値l let you guys know what happens regardless.

nice find! those blank usb sockets look perfect for direct wiring +5v/gnd from an old atx/meanwell /whatever psu with the data/ground wires from an old usb donor cable wired in.

no worries about melting crap 28 gauge usb power wires there.

whats "high power?"

i ran 5 compacs at just under 2 amps each plus an artic usb fan  for months.

did have the artic fan partially aimed at the hub as well as the sticks.

I killed one with 3 futurebits.

and killed another with 4 du1's.

My "controller" was reporting power surging backwards along the usb 3 line into the computer. so I think it has a design flaw.

Great hub until the bed started smelling funny.

I guess in the defense of superbpag they might not be made to run in a 90-105F ambient room.

That's probably the issue- they dont have the best cooling features with just a copper fin and with so much power running through them something might've malfunctioned in the heat.

As I discovered with my 7-port, 60W charging hub from Plugable -- pop it open and look at how the power is distributed.

On the Plugable, it takes 12vdc in and has 3 buck regulators taking that down to 5v  for the USB plugs. That said... 1 regulator feeds ports 1 & 2, the 2nd regulator feeds ports 3 & 4, the 3rd feeds ports 5-7. See where this is going?

After futzing around with 2x of the 2PAC's along with an original Compac just plugging them in 1-2-3 I was unable to run all 3 at decent speed without at least 1 stick dropping out. Looked inside the hub and found ^^ so...

Put one 2PAC on port-2, the other on port-4 and the Compac on port-6 so each stick has it's own 5v regulator. Now the Compac is back up to its usual 318.75MHz and the 2PACs are running 175MHz 225MHz giving a total of 65-70ish GHs pointed at solo.kano.org. Lovin' it Cheesy

Hey man- you know your stuff! I am setting up a 2pac rig with with compacs, what USB port would you go for? I am having the same issue, the power is not evenly distributed through the power hub, had to swap them around- I will have 8 2Pacs and 4 Compacs- so I think I need a decent powered hub.... any ideas ?

I'm running about 200 watts on 10 sticks for 300gh. So I don't think that's overkill, could still use more lol. If you look at the left of my miner you'll see the kill-a-watt. It hovers between 180 - 205 watts.  But that also includes fans, hubs and pi's

So, an update, I underestimated the amount of power I would need by 2X. I have this power supply ordered (5v 60amp) to fix this.
http://www.ebay.com/itm/AC-110V-220V-TO-DC-12V-24V-5V-Switch-Power-Supply-Driver-Adapter-For-Led-Strip-/351769808694

Until then I split it into 2 miners each with its own power supply, pi, hub and 5 sticks



Other than upping the voltage on the 2 sticks with hw errors I'm pretty happy with this speed (1.48v at 300mhz)

Yes, if you don't plan on running them over 100Mhz.

That hub will provide max 0.5A per port. Two fast charging ports can provide more power, but only if the hub is not connected to the PC/RasPi/whatever...

http://i.imgur.com/yX0uaBf.jpg

So you're running the beefy (24ga?) wires from power supply to the two outer posts on the USB connector and then the two inner data wires to the USB hub? Do the male plugs that go to the USB hub only have data +/- connected, do are you doing something with the 5v from that bus, too?

Would you mind providing a closer image of where the female ports connect to the wood supports?

I like this idea and may "borrow" it if that's okay with you...

Those are 18ga power wires on the outside and 28ga data inside.
I don't make them anymore. I make "upgraded" usb cables now.
They were too difficult to make and assemble and I didn't trust them.
I tested 10x patched cables against 10x homemade ends they didn't make much difference.
So now I just "upgrade" usb cables by cutting the power from the hub side, solder in 18awg wire powered from the meanwell.
and stick em in a plastic holder



I made a post in the "I did it" thread with more info. The only real difference is I now cut the both power wires coming from the hub.

So for the last few inches/cm before terminating in the female plug you are running the thinner wire? What's the max amperage you have pushed through the connectors?

yep it goes thinner as it gets to the female end. the usb cables i use are 28awg data and 24 awg power.
basic wire thickness from the power supply is ... meanwell  -> 16awg -> 18awg -> 24awg
 I have put 1.51v @ 300mhz which is about 2.8ish amps. But I am having stability issues so I don't know what i am going to run it at.

Where do you do the split from 16awg to 18awg? I didn't see a distribution block in your pictures, is there one just off screen somewhere?

I don't have good pictures yet. I'm still building it lol. Basically I "upgrade" the usb cable and then solder all 5 18ga wires from a "group" of miners to a single 16ga wire that i then run to the power supply. No distributions blocks just lots of solder and tape Smiley

if you look at it from the top you can see the clump of wire at the bend were 2 groups of miners come together that bundle of tape is where i soldered the wires.

Hi All,

I would like to build similar to this setup:

https://s21.postimg.org/fdfl4forb/miner1.jpg
Picture not mine. Thanks to owner

I will be using the items below:
* superbpag USB 3.0 70 watt hub - I saw on this thread
* 2pcs sidehacks 2pac usb stick
* artic fan
* raspberry pi 3

I would like to know if this will suffice to run for at least a year. Im doing this to experience only (not to ROI)

Also can I also attach the display, just like on the picture?

Thanks in advance.

if you run them for a year, that would do nothing lol and spend  very little wattage.  I have 4 with my 20 port USB 3.0 with raspberry pi 3.0, pulling about 78watts.  that includes 2 usb fans.


I have links of the pictures on the subject of :

ATM I have only one 2-pac and a Nano fury. I have 3 more 2-pacs coming. My question is ...I am wanting a hub that will run all 5 at the same time. Any suggestions?

Yikes! I was going to spend 100 bucks...those look really really good but cant do 200 right now. Any others around 100 or so you might recommend?

Also thank you for answering so fast.

ahhh...thank you...My 2pac is causing cgminer to fail. It gets the message that GSD 0 has failed disabling...It was working great yesterday. Might this be a hub issue although it works fine with the nano fuiry and it has worked with the 2pac in the past.

Downside is those are only 2.0 so you can't do real high ocs with them. That's why I opt for some of the superbpag hubs even though they're not the most durable in the world, I clock my compacs to 300 easily with them.

No, you got it right. The most common USB3.0 ports and hubs can provide a little more current than 2.0 allows but folks have had issues running sticks directly from 3.0 hubs. Since we don't care about the higher speeds 3.0 can run that leaves main requirement as...

The need to simply use a hub that will supply more 5vdc power such as ones rated for 2.1A and higher charging. Look for BC2.1 as  I recall. They are normally used to power tablets/phablets and the better ones will happily provide more than just 2.1A -- but -- look at how many ports and which ports it can feed that power to at the same time.

My attempt at upping the power to my soon to be arriving 2pacs on the cheap. I'm reusing stuff I already had on hand.  I am waiting on my Block Erupters to sell on eBay to reclaim a 5v 40 amp led "meanwell" power supply. My plan is to use Monoprice usb extenders and some 18GA wire to hook up the power of the meanwell and data of a cheap 10 port hub (also hooked up to the meanwell) I hope to get these guys running at 3 to 3.5 amps per.

I slice the jacket and remove the red and black wire (verifying that they are the +5 and ground on the usb ports) Cut the red wire and cap the side coming from the usb hub. Solder in the new 18GA wire +5 and ground cables. Verify no shorts and wrap the solder joints on opposite sides of the usb cable.





I cut some 3/4 wood dowel and using a saw and 1/2 drill bit made usb "Holders" they are spaced 2" apart to allow cooling.
I plan on attaching these to the board that my power supply is mounted to and using hot glue attaching the usb "holders" to the wood dowel.
And then attaching cooling fans.
Will Post more pictures when I get it completed. Just wanted to throw this out in case it helps others.


Looking forward to updates and pictures of your setup.


I did something very similar to this idea and finally got all my miners mining at once Cheesy Cheesy Cheesy.

I'm not able to find the Superbpag hub to ship to Europe. Sad
The Eyeboot 19-port is too large for me as I won't expand the stick mining farm too much, I'm looking for a smaller powered hub to connect directly to my PC (no RPi will be used).

What are my choices for 3 x 2Pacs (I'll run them at 200 MHz)?

Thanks!

I use that exact same Plugable hub. Not sure if you already saw/applied this but bears repeating if someone does not know about how many charger hubs distribute power per-port(s). https://bitcointalk.org/index.php?topic=1779423.msg17921042#msg17921042

Works great but gotta know it's quirks.

One of these days I will take my 2nd one and hard-wire the port power feeds to a single 5V 15A supply but as the old saying goes: The cobblers children have no shoes...
That and at work don't have my usual time for um, other things... For the past week or so really into trying to get a handle on why our $500k laser test bed system's beam is wandering... Not good when trying to hold less than 2オm position tolerances... Narf

I bought my Plugable based on your description of the power distribution. For that, I thank you. I have 3x 2PAC at 175 MHz each on ports 1, 3, and 5. They are humming along happily for a total hash-rate of ~57.5 GH/s.

Dear fellow bitcoin mining enthousiasts,

I've recently bought 4 Gekkoscience 2Pac's. I would like to use them together with the Gekkoscience Compac I already had. So for the moment I'm looking for a suitable powered usb hub that ships to Europe and that is compatible with the laptop ( runs Ubuntu server 16.04 LTS) I use for the bitcoin full node. The laptop is a relative old model (about 5-6 years old) and has only USB2.0 ports.

I've seen a mining setup on this forum that uses a Sipolar A-300. Is this a good hub? I've read comments about this hub that the amps per port are a bit low. Would this hub allow me to overclock the five miners?

An alternative hub I'm considering is the Sipolar A-210 (https://www.alibaba.com/product-detail/Industrial-High-Power-USB-HUB-20ports_60343874449.html?spm=a2700.7724838.0.0.ZsEEgx). This hub should deliver 1A per port. Has anyone of you experience with this hub?

The Plugable 60W hub that has been suggested looks also interesting, however I doubt whether it will be sufficient to power the 5 overclocked miners 24/7.

Or, do you have other suggestions that would allow for overclocking, and are acceptable for my budget (at most 100 euro or about the same in dollars)?

Thank you in advance.

Sincerely
NotFuzzyWarm

That specific hub actually is maxed running just 3 sticks and you MUST make sure each is plugged in so it is 1 stick for each of the 3 regulators in it. Just will not have enough power any other way so more than 3 on it is out of the question.

I bet you could run 6x 2PAC if you set the voltage to the lowest value and only run them at 175MHz. You would only pull about 6.2W per compaq which should keep it well below each regulator's maximum and you would still get about 115.2GH/s overall.

Thank you for your reply. So it is not advisable to run 5 on them. I've also read your previous posts, it does indeed not look very good. Then my options are using two Plugable hubs or one more powerful one.

Thank you for your reply. Is this solution something that would work reliably 24/7, or can I expect a lot of interruptions? I'm fairly new to bitcoin mining. I've used in the past an Orico 10 port usb 2.0. But even with only one compaq attached I could not get the speed of that compaq above 12 GH/s. So that was quite disappointing. So now I'm looking for a setup that has been tested before and that is very stable.

And the House wins.
Care to play again?

Been there, tried that. Even with the sticks at OEM default of 100MHz it would not do it. Tweaking Vcore and speed, still no go with 3 sticks so forget about running more. For hubs NOT designed expressly for stick miners it seems that any power rating given is more of a suggestion than reality if you actually want 5v out @ rated power per-port.

My guess is that yes, a normal or a 'charging' hub *may* be able to provide rated wattage but it will NOT be with 5vdc coming out but instead the voltage will be lower. Maybe charging circuits don't care but the sticks do. The regulator in the sticks cuts off when incoming voltage goes below 4.4vdc. Even at the default 100MHz sticks were dropping out so....

That probably explains why I was only seeing 4.86v on each stick. How hard are you pushing your 2PACs? I was hoping to expand to 6x 2PAC, but since that seems impossible on this hub, I might as well push the ones I have a little harder.

Hi guys,

A little bit off-topic and probably silly question: do you think a laptop cooler would be okay to use as a solution for the 2Pacs?
I was thinking to sit the hub & sticks on this Deepcool N200 cooler, I'm assuming it would cool better than a normal USB fan.

so lay hub on its side        I think it is not ideal  as I think  the air moved by the cooler will not flow fast due to small grill.  I found one on ebay  for  22 usd

http://www.ebay.com/itm/Deepcool-N200-USB-Cooling-Stand-Pad-cooler-mat-For-Laptop-Notebook-10-15-6-/151877092837?



seems to me this would work better  and it is 18 usd

http://www.ebay.com/itm/Holmes-10-inch-Personal-Size-Box-Fan-HABF120W-/142100873644?

better yet this one is 9.99

I'm just brainstorming here, maybe we can come up with a more efficient, cheaper & better-looking cooling solution.
I can get my hands on the N200 cooling stand for approx. $8, same price as the Arctic but with (theoretical) better cooling performance.

The hub I will be using is the Plugable USB 2.0 7-Port Hub, so actually it won't sit on it's side.
The sticks - indeed - would be cooled on their side which concerns me from the efficiency point of view. What do you guys think?

Thanks.

Once a fan is used the orientation of the heatsink is a moot point unless it is one very tiny low-flow fan. Keeping fins vertical only matters with convection cooling.

I do hope you have read my earlier posts about the power layout of the Plugable 7-port hub...

               ------------- >> cooler

I think  the hub blocks air flow  to the sticks if he lays the hub on the fan and points sticks up wards

I did read it, and it helped. Thanks for the tips!

Almost, here is a simulation of what I have in mind.
At $8 I think I'll give it a shot and monitor the temps. If it works out then great, if not, I have 30 days to return the stand. Smiley



I'll keep you posted, my 3 x 2Pacs should arrive shortly.

For those trying to mine with 2Pac's and RPi's this 5V 4A hub from Amazon Basics is currently running two 2Pac's (not overclocked) through an RPi3.  Hub is USB 2.0 and is the only one I've had success with out of the 4 I own.  The ports on the front are higher current so it might even support a third stick but I only have 2 atm.

1) Hi Guys, I have a shit HUB, powered with 3A (at least in specifications), when I plug my Gekko directly in notebook port, I can mine at 200 mhz fine, but when I plug into that Hub, it even donエt start to Mine. Can I throw it away?

2) Another question, is it preferable a 3.0 USB hub or a 2.0 USB Hub?

Why would you throw away perfectly good hub? I would just use it for other stuff. You should get a USB 2.0 hub. The results from USB 3.0 hubs are sketchy at best.

It'd probably work, amps per port is decent if you can connect devices through the yellow ones on the hub. As for a fan, although most people like the 1 dollar loud USB fans, I prefer the more expensive desk fans. Decent airflow and keeps the sticks happy.

I Was Wondering, a 10 Ports hub like this: http://www.orico.cc/goods.php?id=6225
With a 12V3A power, this mean a 36Watts, How this Watts are distributted to ports?

36Watts means 7.2A in a 5V, but are each port limited to an Amperage? or if you connect 3 ports only, those Amperes will be splited into these 3 ports?

USB 3.0 is sketchy with the Compac and 2Pac sticks, so try sticking to USB 2.0 hubs. I did some looking around on the aliexpress site and came up with this one:
https://fr.aliexpress.com/item/LVSUN-120W-5V-24A-10-Port-USB-Charger-HUB-USB-3-0-Chipset-with-Data-Transfer/32640377816.html

You can put the two 2Pac miners in the 2.4A USB Hub ports (there are four total data ports) and you can plug the fan into one of the other non-data ports.

It's not cheap, but then his current ports that also pass data are kind of odd and are scarce.

Cheers,

Hum itエs nice, I havn't found this brand before, seems pretty good.
But for the price range, I think the Orico 20 Ports 300 Watts itエs a best deal: https://www.aliexpress.com/item/ORICO-30-Ports-Industrial-USB2-0-Hub-for-TF-SD-U-disk-Data-Test-Batch-Copy/32812709736.html

Only .5A a port is pretty bad, to my experience I have run these miners just fine on 3.0 hubs. They cost a little more than 2.0 hubs but they're necessary for real OCing. As for the brand, ORICO is a decently good manufacturer of hubs. Never had issues with them, just always make sure to check amps per port.

I have that exact hub, and am having all kinds of stability problems (miners won't run for more than six hours without going zombie). See the main 2pac support thread for details. Don't know if it is related to the hub, but if I were starting over again, I would be looking at something else.

I Think this usually means that in sometime there was not enough power to run them, so they  went zombies. Try lowering frequency in 10 or 20 mhz, and lower just a little bit the VCore, and see whatエs happen.

Actually you made me think that in my house, I have a really unstable power source, it usually loose power in a flash moment, these kind of thing would make the sticks goes into zombie mode!

I've been running four of the 2Pacs @ 150MHz on this Sipolar hub (https://www.amazon.com/Sipolar-USB2-0-Bitcoin-Indicator-Powered/dp/B01K4LYX7U) with no issues.  I haven't spent a ton of time fine tuning them but my initial attempts to run them at 200MHz didn't work, seems like the draw is too much for the individual ports.  I haven't tried each stick one by one in each port but I will post an update when I do.

OK tested with this new little Eyeboot 2 port usb hub extender/splitter (only $14.99 usd from Amazon with free shipping);

https://www.amazon.com/dp/B07281L7QC




It comes with 5V 2 amp power supply so has everything you need out of the box.




First I tested it on 100 mhz and got a speed of 11.14 GH and a power draw of 1.1 amps









However I did my own test on the hub and found the max power draw (per port) possible is 1.5 amps (see pic below)




So I decided it was safe to overclock the miners. Here are the final results;

At 150 mhz we get a speed of 16.41 GH



At 175 mhz we get a speed of 19.51 GH



At 200 mhz we get a speed of 21 GH




Pros: it is cheap and cheerful. can boost the power of any usb port it is used with. includes 3A 5V power supply
Cons: shape means it can only run 1 usb stick. power draw is limited to 1.5 amps.

I have on order a Sipolar 30 Port.   
https://www.amazon.com/Sipolar-Charging-Station-Charger-Cabinet/dp/B01KPQJRAW 

More power than you'd normally require but should be useful for what I need.

That 5V/60A psu layout caught my eye.   I should be able to tap into for other things.

Also Based on the layout the hub may be able connect to two system simultaneously.

I'll post some updates on it when it arrives.

So, possibly stupid question, but I'm new to this.

I'm currently running a pair of 2PACs at 150MHz with Raspberry Pi controlling them.  I can tell ample power is a constant issue.  I have one clearly substandard USB hub that is powered, but only has a 2 amp power supply.  If I try to run both 2PACs on it, eventually one drops out.  I can however run 1 off the Pi unit itself, and one off the hub.  But that is less than ideal, especially since I'd like to clock them higher.

I have another powered USB hub that is not compatible with Raspberry Pi, but which has a 3 amp power supply.  On a scale from "Go for it" to "You're gonna fry you 2PACs", how bad of an idea is it to just use the 3 amp power supply with the hub that normally uses a 2 amp power supply?

Alternately, I did order a Sipolar 10 port HUB, so I could just wait for that to eventually show up from China, but I've caught the bug a bit...

The 2Pacs should be okay as long as you are not up-ing the voltage and frequency and pushing it to work harder than its default settings.   The hub might give out first if you draw 3A through it though.   

There is some notes on the first page of posts about daisy chaining hubs to overcome some specific hub incompatibilities with the pi.   It might or might not apply in your case.

I think there are a lot of unknowns with your question. It is hard to make a judgement call regarding your hub and 3A power supply. One of my concerns would be does your hub and power supply both use barrel connectors or micro/mini USB? If it uses a barrel connector, you need to ensure that your polarities match between the two and that they are the same size.

I have it plugged into my Pi3B and have mined steady through it for 24h.

Sipolar 5V 2.1A 30 Port USB 2.0 HUB

Pros:
  • Very sturdy.  No flimsy feeling parts.
  • Works excellent with the Pi3B.
  • Split Hub chain.  Can connect 15 ports to 2 different systems, or 30 to one.
  • Tested a few ports drawing 2.5A with no issues.

Cons:
  • Power backfeed out USB-B ports.
  • VID:0bda PID:5411 - Realtek Semiconductor Corp Controller.
    • No Windows 7 driver.
    • Compatible id comes up as Generic USB.
    • cgminer reporting write errors.   TBD.

If it uses a barrel connector, you need to ensure that your polarities match between the two and that they are the same size.

They both use barrel connectors, and the polarities are the same.  I was slightly mistaken about two things however.  One is 5V, 2A, and the other was 5V, 5A.  Regrettably, I was also wrong about connector compatibility.  One is just ever so slightly larger than the other. 

I attempted to daisy chain them as well, and still no luck.  The Pi doesn't recognize anything at all plugged into it.

I'll just have to wait for my sipolar 10 port to get here.  It's encouraging to see other people have had good experiences with it.

I want know require spec for using multiple sticks.

Is it enough only 12V 5A ?

Do I need to check each port how many support ampare?

Each port supports 2.1A,should be sufficient for a small overclock on the chip. Should work with 4 sticks. If each port is also 5V then the power out is around 10W, check the 2pac thread for an OC chart.

It won't work, because when you remove the data cable (read on product's description on Amazon) the ports will provide the amps but NO data transfer capability.

As long as the sticks run at the the default 100MHZ - maybe.
That page says the power out (assumed per-port) is only 5V 600mA which is the output of normal non-charger USB ports/hubs. To push the sticks to higher freq means more current needed, as in up to 1.5 to 2 amps per-stick.

New here, new to the 2pac.   But glad to see this miner still has active discussion.

I have 4 2pac's
I have an Anker 7port powered 3.0 that I currently use for 2 Futurebit Moonlanders and an Artic Breeze and they work great on it.
https://smile.amazon.com/gp/product/B014ZQ07NE/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

I'm just testing the 2pac's to see if I can get all 4 working on the same Anker 7port to see if I should buy another
No luck

I'm using XP 32bit, USB2.0, did the Zadig
I can get 1 at time working easily, with a 150 freq setting.  So my thought is it's the hub or the .bat

I played around with unplugging and plugging in intervals and am able to get 2 out of 4 working,  but not always the same 2 (I know, fun right?)

I did the cgminer.exe -n , found my multiple Bus # Device #  thinking I could specify each USB device with a --gekko-2pac-freq 150 --usb #:# (4times)
which took it back down to 1 working
I can see them all in my device manager
Can you specify COM port instead of bus:device?
It's weird that cgminer will only start 2 of them

If it is the hub, what powered hub is recommended for 4 2pac's and a fan? planning on an affinity 120mm fan

These things are really finicky

You gotta consider a 2Pac at 150MHz is going to be pulling about 1.4 amps. That's not insignificant.

so drop the freq and/or get a more powerful hub?  suggestions on hub?

FYI,  I feel like an idiot for not realizing that it had to do with power per port.

UPDATE:   I dropped them to freq 25 and all 4 worked fine.  Time for a new hub.

FYI,  I feel like an idiot for not realizing that it had to do with power per port.

I almost bought the 10 port Sipolar hub a few posts up that only provide 0.6 A per port.  Luckily I was able to cancel my order.  I must have been looking at hub specs so long I'd gotten confused about which hubs had which specs when I ordered it.  Maybe I got it confused with a different Sipolar 10 port model that did provide 2A per port.  No idea.

I'm currently running a pair of 2PACs on a Superbpag 7 port hub which is rated at 2A per port.  I have them up to 225Mhz which is as much as I dare with my current cooling solution.  Going by the spreadsheet on post 1 of the support thread, that should have them pulling something like 1.75A, especially since I have the vcore tuned as close I could without hardware errors.  But I suppose it could be a bit above that.  The heatsinks are warm enough to be uncomfortable to the touch, but not immediately yank my fingers away.  So I think I'm ok.

I'm hoping to get a few more 2PACs and then we'll see how well the hub holds up.  I think I read elsewhere that running this hub at 100% capacity with poor ventilation for extended periods killed it pretty hard though.  So we'll see how things progress.

I'm reading the same about the superbpag 7port

capable of 2A per port, but that they die out if overloaded.

It seems the only hubs with higher power are the eyeboot options.  I was hoping to not spend so much on a hub, but maybe it's a sign that I just need to buy more usb asics! Shocked Cheesy

UPDATE:
Or maybe the better cheaper option is 2-3 superbpag hubs in a daisy chain? so there's only 2 devices per hub.  anyone done that?

After a days of testing this Hub klintay generously shipped over,
https://bitcointalk.org/index.php?topic=1779423.msg19508324#msg19508324

here is an initial summary of the unit:

Eyeboot USB Mini 2-Port USB 2.0 Hub Splitter

Pros:
  • Works with a single 2Pac out of the box on Linux (Pi3B) and Windows.
  • 5V 3 Amp power adapter
  • No power backfeed.  Won't mysteriously keep components awake when the PC is off.

Cons:
  • Can not run more than one 2Pac (with right angle adapter)
    • Voltage starts a bit low @ 4.7V with one 2Pac connected.
    • And begins to drop as load is applied 4.3-4.7V.
    • A second device connected and running amplifies this drop < 4.3V.

I'll update this post with more details and some photos as it becomes available.

I don't see why you shouldn't be able to plug them into different ports on the computer or daisy chain.
Not with this particular model, but I've had multiple hub connected in both configurations without issues.

That is not a hub. It is a charging station. If you read the description carefully, it says as much.

I got my 10 port from aliexpress, the data rates were included in the full product spec's when i purchased it. Look on the Sipolar web site for details.
https://www.aliexpress.com/item/Sipolar-high-quality-usb-2-0-hub-power-supply-usb-hub-10-port-usb/32705044739.html?spm=2114.13010608.0.0.mF9xrG

The amazon one in the picture also doesn't have a up port.

Hello All,

Sorry newbie here. Need your advise.

For simplicity, may i ask to share your hubs that works with multiple 2Pacs or even with other USB Sticks.  If possible, kindly advise where u purchase it too. Negative and Positive remarks will definitely help to avoid failed purchase.

Example

1. USB HUB NAME -
$xx.xx -
Purchase it here.. 
CONS:
PROS:

I am looking to buy one to work with a minimum of 2 to 8 2PACs.

Thank you all in advance.

4 2pacs will fit in this superbpag https://smile.amazon.com/Superbpag-Portable-Charger-Transfer-Samsung/dp/B013OK10YM/ref=sr_1_1?ie=UTF8&qid=1498654958&sr=8-1&keywords=superbpag

so you would need 2 hubs

others may use different hubs, but I found this one to work for me

Oh cool, I just found out about USB mining and now there's a thread! Smiley I have some questions, though..

1. Where does one purchase USB miners?
2. What is they power and/or resources (CPU, RAM?) usage?
3. Are they worth it? I have in mind that I would like to mine altcoins, namely LTC I think.

You almost hit the right thread, this one is for what it takes to power them.... Try GekkoScience 2Pac BM1384 Stickminer Official Support Thread for all your answers. These days stick miners are only good for Solo Lottery mining as they are too under-powered for most pools to accept.
btw: the sticks ONLY do Bitcoin -- not altcoins.

Not all sticks, I have futurebits that are daily profitable for scrypt, by 10cents or so after electricity. but upfront cost is so high on sticks that ROI will be 20years or so at current difficulty.

Most pools accept shares from my Compac, 2pac and even Antminer U1s. Of course you won't make much, but it's always fun to get some dust rewards. Solo mining is by far the best way to use stick miners as it's your only (small) chance to get anything from them these days.


Also, my Eyeboot 2-port 5v3a USB Hub is here! Pics coming in later. 2Pacs not liking either the voltage I have on em or the power (300mhz), but I will still post initial results.

Pictures:






Thoughts: 2 ports are a little too close to each other (possibly allowing for only one miner to run at once). Compac + 2Pac works fine as the heatsinks face opposite directions, but 2Pac + 2Pac does not as the heatsinks are too big.




The red LED on the hub itself is a little bad in my opinion as it shines pretty much through the shell of the entire hub, but that may be because I just don't like LEDs at all Smiley

Design is good and solid plastic, and the included power adapter doesn't have an obnoxiously bright LED, unlike most Chinese power adapters I have owned. The fact that it comes with a power adapter of substantial power is good already. It is capable of powering a 2Pac at a minimum of 300mhz if you find the best position for the voltage to the ASIC. I will find the numbers for the Compac later.

(Sorry for the way-too-big first image, switched image hosts until I found the best one).

Is this the only hub capable of running 15-19 2PAC at 2amp at the moment ?

https://www.eyeboot.com/19-port-40a-usb3-hub.html

Or is it better to use 3x 7port hub with same power output ? Like this one

It looks like you need about 14W per port to run at 300Mhz. So, a 7-port data/charging hub with 2.1A per port should be able to run at 250 MHz? 5V * 2.1A = 10.5W...
Wondering if a 70W charger/hub like this https://www.amazon.com/Plugable-Charging-Adapter-Support-Android/dp/B00L2LK164/ should be able to run at 250MHz wouldn't you think?
It does say it's a data hub, so it should work.

Hub enables connecting 7 additional USB devices. Forwards and backwards compatible with all USB 3.0, 2.0, or 1.1 host controllers and devices on Windows, Mac, and Linux/Unix computers at USB 2.0 speeds up to 480 Mbps. Transfer rates are device and USB host controller dependent. Fully plug and play, devices can be hot-plugged, supports USB over-current protection. Requires no driver installation (although individual devices may require drivers).
I don't know exactly how the power is distributed into chains inside the hub, assuming that I would need a full 10W (5V * 2.1A) per port.

re: the Plugable hub and PM about pullin more power out.
All should see my reply which is:
Does not work. Been there, tried that. Each of the 3 internal regulators is only good for about 1.5A before the voltage out drops below the USB spec of min 4.4V. If voltage drops below that the regulator in the sticks turns off until it is reset.

Charging applications really don't care but powering a device via USB does care very much.

If I took a switching 5V 15A PSU, I should be able to wire all the power pins on any hub (which has easy access) to get the required amperage?
That would get me the required amperage.
If I read it correctly, 250MHz draws around 2A per port (10W / 5V = 2A). I should only need 10A to power 5 2Pac rigs.

Yep, would be perfect. Cut the internal power traces near the sockets so the logic drivers part still work and pigtail each power connection out from the socket pins using say 20ga wire and tie together at the supply. That way each socket can get full power if needed and not really affect the others.

Been thinking about doing that with an Intersil monolithic regulator dev board I have. The board is about the same footprint as the Plugable hub so they would stack very nicely... Given a healthy 12-24V main supply it'll put over 50A @ 5V Wink  Too much at work to do so just have not had the time to do the admittedly small amount of wiring needed.

As the old story goes: The cobblers children have no shoes...

Hi All,

I got now my 2 x 2pac usb from Klintay (eyeboot). Thanks

https://image.ibb.co/fPr9HF/20885028_10204007029371872_1618840630_n.jpg

My question is I have now 2 usb and 1 raspberry pi 3. What is now the best hub to use in this kind of setup?

What is the program/app should I download/run in order for it to start mining?

Thanks in advance

Hi, I'm newcomer. I just used Gekkoscience to mine BTC so I get the problem when cgminer running with 2 more Gekkoscience.
When I put 1 stick on hub usb => it's working good
But when I put 1 more on hub usb => the first one will degrease the hashrate and degrease to Zero => it will show Zombie
I have some pic when I get the problem. Pls help me

I'm going to take a guess and say that your hub is underpowered. If the hub doesn't have any power input from a power brick then it is not usable for more than one Compac, and if it doesn't have enough input power it won't work either. (Just looked at it, it indeed is the issue).

In my experience these hubs work pretty well for mining but their lifetime and build quality might not be the best.https://www.amazon.com/gp/aw/d/B013OK10YM/ref=mp_s_a_1_1?ie=UTF8&qid=1503832033&sr=8-1&pi=AC_SX236_SY340_QL65&keywords=70w+usb+hub&dpPl=1&dpID=31WLrxeZrqL&ref=plSrch

At this price point though, this is hard to beat. What you are looking for in mining hubs is high output per USB connector and lots of wattage for the entire hub (wattage is volts x amps)

As I discovered with my 7-port, 60W charging hub from Plugable -- pop it open and look at how the power is distributed.

On the Plugable, it takes 12vdc in and has 3 buck regulators taking that down to 5v  for the USB plugs. That said... 1 regulator feeds ports 1 & 2, the 2nd regulator feeds ports 3 & 4, the 3rd feeds ports 5-7. See where this is going?

After futzing around with 2x of the 2PAC's along with an original Compac just plugging them in 1-2-3 I was unable to run all 3 at decent speed without at least 1 stick dropping out. Looked inside the hub and found ^^ so...

Put one 2PAC on port-2, the other on port-4 and the Compac on port-6 so each stick has it's own 5v regulator. Now the Compac is back up to its usual 318.75MHz and the 2PACs are running 175MHz 225MHz giving a total of 65-70ish GHs pointed at solo.kano.org. Lovin' it Cheesy


https://www.amazon.com/Plugable-Charging-Adapter-Support-Android/dp/B00L2LK164/ref=pd_sbs_147_2?_encoding=UTF8&pd_rd_i=B00L2LK164&pd_rd_r=2KEH574PN7ZYFVFXHXSE&pd_rd_w=lEXyf&pd_rd_wg=h8kAR&psc=1&refRID=2KEH574PN7ZYFVFXHXSE


is this the one you're talking about?Huh

I need to find a good hub to power both my 2pacs and maybe a 3rd one.

if this is not the one..... any suggestions on a good hub to run 3 "2pacs"Huh

Noob here, having some trouble chaining my USB 3.0 hub to RPi 3 with a 2.0 hub (Noticed it was mentioned earlier).  The hubs seem to chain together fine when hooked up to my PC but my sticks aren't detected when chaining with the Pi.  Not sure what I am missing, maybe  my 2.0 selection was poor?

Trying to find a USB Hub for my 2 2PACs and my RPi3.

All the links I have seen here are mostly pointed to Amazon. A lot from Amazon is not shipped to Denmark.
Could someone help me to find a USB hub that will fit the 2PAC and can be shipped to Denmark?

I'm not trying to be lazy, but I can't figure it out.

So click on the links that are provided, copy the name, model number, description, or whatever, then search for that info on your favorite online seller that does ship to Denmark. I would imagine that many of the same products are shipped around the world, and perhaps the only difference is the power supply that feeds the units. And that might be for local laws regarding safety approvals.

I trying to understand this, if you have max 3 2PACs sticks, this hub will be able to complete the task by adding them to Ports 2, 4 and 6.

https://www.amazon.com/Plugable-Charging-Adapter-Support-Android/dp/B00L2LK164/

If you have more than 3 then it's a hub like this that have to be used:

You could also get two of the pluggable hubs and run them from one Pi, but yes, you're right. I'm using the 20 port one to run 7 2PACs .

Noob here, having some trouble chaining my USB 3.0 hub to RPi 3 with a 2.0 hub (Noticed it was mentioned earlier).  The hubs seem to chain together fine when hooked up to my PC but my sticks aren't detected when chaining with the Pi.  Not sure what I am missing, maybe  my 2.0 selection was poor?


I couldn't get my Anker's (I have 10 port models) to work with chaining at all.  Ended up buying some of these https://smile.amazon.com/gp/product/B01ALLWDFW/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 with the data cable connected to a 2.0 Superbgpag and the other to the Ankers for power.  
Could you add a picture of that setup, please?


Just a thrown together desktop setup to tinker with when I need a break from work really.  Actually working on it now, so it's slightly sloppier than normal, but not by much.  

There are two Ankers here, neither send data, just power. Data cables all go to the Superbpag.  The one in the front powers the two fans and I have one of the 2Pacs power-only cable running to charging power at the moment to test running all 7 at 300 (I have one plugged in to the charging only port on the back Anker as well).  The Anker in the back has the other six power-only cables attached and is hanging by the cables so that the 2Pacs are slightly angled from tension on the cables - I did have to play around with which connections for which 2pac worked best.

RPi3 is connected only to the Superbpag (and HMDI, keyboard, mouse).  Pi freezes occasionally with this setup and has to be restarted.  I think it's an issue with power (or PSU) going in to the Pi, not the USBs, but I'm not sure as I haven't taken the time to look at that yet.

The wire mesh basket it's hanging over is just something I happened to have lying around unused that fit the bill.  I originally tried to set this up with everything mounted upright using a Vans shoe box my son had.   : ]

Thank you for your answer.
Has it been confirmed that you can more than 1 pluggable running from 1 Pi?

Can the 20 port run more than 7 2PACs?

Can you add a picture?

Hi,
Thanks for the info here about hubs for Gekkoscience sticks. I have read through this hub topic and the 2PAC topic as thorough as possible. I'm not an electrical engineer so please excuse me If I write nonsense.

I would like to experiment with some stick miners and I have some questions about USB Hubs. The newest one in the bundle is 2PAC (from Bitshopper de). The other ones are older (RedFury style etc.). The plan is to connect them all to 1 USB Power Hub.

I'm located in Europe so the options for buying a good USB Hub are limited (unless you want to pay some serious import taxes). I have narrowed it down to 2 products:
  1. Plugable USB 2.0 7-Port High Speed Charging Hub 60W https://www.amazon.com/dp/B00L2LK164/
  2. Anker 60W 3 PowerIQ Hub 7-Port USB 3.0 https://www.amazon.com/Anker-PowerIQ-Charging-Macbook-Surface/dp/B00VDVCQ84/

This topic already contains plenty of info about the Plugable Hub, thanks for that.

The Anker hub specifications:
  • It is a USB3 hub.
  • 12V 5A AC Power Supply.
  • Provides power -simultaneously- to max. 3 ports up to 2.1A, and 0.9A for all other ports.

The hub will be connected to a custom low-power Mini-ITX Linux Server which I use for various purposes, with an ASRock H110 Skylake motherboard and a Pentium G4500 cpu and 16GB of memory. The box is powered-up 24x7.

I plan to connect 2-3 2PAC's (not overclocked) to the USB Hub and fill up the other USB ports on the hub with older sticks and place a 120mm fan alongside the hub.

The older sticks are all < 0.9A.

The hub (USB3) does not have to work with a Raspberry Pi.


I have some specific questions about the Anker hub.

Q1: Is someone using this hub, do u recommend it?

Q2: Do you think the hub can handle this setup (2-3 2PAC's and 4-5 older sticks)?

Q3: Are the specs of this USB3 Hub (2.1A on max 3 ports simultaneously) also valid if you hook up a USB2 device such as the 2PAC?

Q4: Are the specs the same if I connect the USB hub to an USB2 connector on the Server motherboard (opposed to a USB3 connector)?

Thanks.

***UPDATE#1*** The three 2.1A ports of the Anker 60W are charge-only so they do NOT support data transfer. This means that this Anker hub is not suitable for the stickminers. I will go with the Plugable USB.
***UPDATE#2*** The USB Hub Plugable USB2.0 7-Port 60W arrived today and it is working fine. Thanks for the info in this thread Smiley

Spotted it last night browsing though Best Buy while waiting for a movie to start. The package claims 3.6A per port. And the price is right on par with Sipolar and other manufacturers making high-power-output USB data hubs.

Don't have experience but if you read the Q&A's the first one states:

"Only one of the ports is 3A, the others are 0.5A ports. Be aware that the full capacity is 3.5A so if you have a device that truly pulls 3A in the high power port the other ports will have diminished capacity."

4 ports / 3.5 = 1.14 max as I see it.

I have a question about the Blue Block Erupter 49 port Hubs - The description on the website and eBay say:

"This is the most up to date version (V3) of the popular USB 2.0 hub, it has new improvements such as a built in 70A fuse. It is capable of supplying 0.5 - 1 amp per port. "

I have two of them and and they both came with 50 amp fuses installed (blade type replaceable).

If you take 50 amps and divide the 49 ports then it comes out to right around the 1 amp per port as they describe. However if these are the "most up to date version (V3)" and is designed for a 70 amp fuse then that would come out to nearly 1.5 amps per port.

I do not plan on filling the entire 49 ports per USB hub.

Main question is - is this blue block erupter 49 port hub limited by the chipset so that even replacing the 50 amp fuse with a 70 amp will make no difference or possibly did they just ship them with 50 amp fuses that they have in stock, and are actually capable of the 70 amp total.

I got an ad for surge protectors/USB chargers and had a thought.

I have four 2pacs.

If I got four USB 3 Y cables, two of these power blocks, and any old el cheapo USB 2 hub, I should be in good shape, right?
Power blocks:
http://a.co/3uJgw5y

I could connect the 2pacs to the female end of the Y, connect the power side of the Y cable to the power blocks, and have data sent through the USB 2 hub through the data side of the Y.

It could work, right? From what I read, each of the two USB ports on the power block supplies 2.1A, which should be enough to power a 2pac at around 225-250Hz at the right voltage.

Thanks.

don't use the 50 amp  find a 35 amp  


and what are you going to power it with?


it looks like it has a 24 pin  jack  and nothing else.

almost no atx  psu  provivdes    40 amps at 5 volts .

So with a 50 amp fuse  you can kill the atx.

Show me an atx better then 40 amps of 5v

most are 25 or 30 amps see below

Or you get a 5V PSU and wire it to an ATX jack. Two of my test stands are set up like that.
