Been trying to run my U3's for a while now, with a powered USB hub as well. Bought an Icy Box IB-AC611.
Does not seem to be a good idea however.
1) i plug in only the U3 that works best: a lot of plug/unplugs to get it up and running with cgminer. Averages at 45. Zombies very very fast
2) i attach the same directly to the laptops usb 3 port. averages at above 60. not stable, but maybe zombies only two times a day
3) I plug both into the hub at the same time: Always gets an error saying the last unit attached on usb was not recognized by windows. hence never get the two units up via the hub (device descriptor fails)

Weird thing with nr 3 is that i then might get the one nearly working unit up and running when windows disables the other usb connection, and i then get a higher average than 1), more like above 60.

So thanks for the suggestions Dogie, didnt solve all my issues however. I like everything else with this unit, so please just make a version that actually works well too Wink

That's a USB 3.0 hub, are you plugging it into a USB 2.0 or 3.0 port on your computer?

Unfortunately there isn't a science to getting these to work, so if its not working without a powered hub, its time to try a powered hub and vice versa.

Tried both 2 and 3.
