Hey guys, I've been wondering what USB hub I should use for Antminer U1 and Antminer U2. I'm currently using Sabrent 10 usb port hub and I don't believe it's working well because not all the usbs are recognized meaning they're faulty and I don't get the full ghs out of each miner or my hub sucks.
That is probably because the hub does not provide enough power for 10 Antminer U1/U2s.
This is very likely. Pretty much every USB 2.0 hub doesn't come with enough power to run a full set of Antminers U2. Keep in mind the Antminers needs about 0.5 amps of power. To fill a 10 port hub you'd need about 25 watts total power. The last 10 port USB 2.0 hub I got, has a 5V, 3 amp adapter. That's about 15 watts (volts x amps = watts). So you can see, there isn't enough power to run a full set.
I just ordered this from Amazon:

In this case a 3 amp one. So that's 36 watts total power available. Take note that I said most, I have seen some come with a 5 volt adapter. Stay away from those. Anyways, we'll see how I make out with this one.
