Amazon has their own custom built 7 port usb 2.0 hubs with 5v/4a adapter for $19 shipped (prime). Ordered 7 for an antminer project, i'll report back how they work out.

Actually they were $12 at some point ... I should've ordered more of them at that time. I've been using them for testing various quantities of NanoFury boards and so far they've been performing pretty well.

A follow-up :

I've been using those Amazon ones for testing of the dual-chip design and I am very impressed by them - I've plugged them into USB3 ports and 3 miners are happily hashing there when pushed to the limit.

And a very disappointing observations from this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16817111981
(and there are a lot of similar ones with 2.5A power brick)
The power brick is a piece of junk and as soon as you add some load to the hub (let's say 1-1.5A) the voltage drops to 4.6-4.7V and if you push it even harder it goes even below 4V.
This was a nasty surprise for my desktop which in essence ended up having to provide all the power as that power brick's voltage was well below the PC's 5V.

Hi do you recommend me that usb hub for mining with antminers u2+? or what usb hub can you guys recommend me? because antminers u2+ have heat sink and are harder to fit Wink

thanks

I just bought Gearmo USB 3.0 10 port hub from Amazon. It comes with 12V, 4 amp power supply. I know Amazon says it's a 3 amp one but I got a 4 amp one. Amazon has it for $33 and is Prime eligible. I just finished hooking it up and was able to plug in 10 Antminers U2's and there is a bit of a gap between each miner. Very nicely arranged. Also there is a power button on the side. It's a small thing but I like having that.

I'm running bfgminer running them at x0A01. I'm getting around 20.5 GH/s right now. I can get a bit more if I'm not also mining X-11 coin using my vid card.

I'll see if I get a pic with the Antminers plugged in and running.
