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

[ZedZedNova]

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 found that Amazon have a UK division too. They ship to Denmark.
Thank you for your answer.

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.

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

Just tried the atolla 7 port usb 3.0 hub i am returning it because it is zombifying my 2pacs.

[marc206]

so not even sha256 altcoins can be mined with these sticks. I bought them thinking that i could mine other altcoins. shit does anyone want to buy 4 2pacs?

You can mine any SHA256 coin with these. Digibyte, Namecoin, Peercoin, Bitcoin Cash, etc etc

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.   : ]

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?

[wavelengthsf]

I've been using the Sipolar 20 port to run 9 2Pacs @ 200Mhz





This is the hub:

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

Wanting to run 5 2pacs on something like the following. Anyone else got one ?

Does anyone have experience with this hub?

https://www.bestbuy.com/site/insignia-4-port-usb-3-0-hub-black/5631038.p?skuId=5631038

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.

[TheNerdyType]

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

[sidehack]

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

I did something similar with a single 2.1A charger and a Y cable and it worked just fine.  My only concern with your setup is whether the power supply can supply 2.1A to BOTH ports at the same time.

The description says:
"Two USB ports (2.1 Amp shared)"
