Now that usb sticks are being sold by sidehack here is a new usb hub thread.

Hi Guys, How about this Orico Usb3.0 60w  5A Usb Hub with 13 ports?
https://www.aliexpress.com/item/ORICO-60W-12-Ports-USB-3-0-Hub-including-3-BC1-2-Charging-Port-and-4/32774929010.html

I´m planing to connect 3 sticks(2 pac BM1384) and a USB Fan.

Also for me, living in Brazil, it´s easier to buy in aliexpress than amazon (they don´t ship to Brasil most of products)

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´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´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´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.

10 running on Sipolar 150MHz(1 2pac keeps dropping out)



10 running on Sipolar 175MHz

[klintay]

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.

[klintay]

We are giving away 5 pieces of the Eyeboot 2 Port USB hub, see the thread here;

https://bitcointalk.org/index.php?topic=1962973

You must however agree to the following;

1. you will write an honest review about the hub
2. take pictures or video showing how you use the hub
3. post review on bitcointalk or youtube or your own blog

Only 1 piece per person. Those with Hero/Legendary status on the forum will be given priority.

Wow, that is a pretty interesting hub splitter. Let me know if you are short on testers/reviewers.

[vh]

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...

[vh]

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.

Can I use this hub with 4 of 2pac sticks?

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.
