Done some more testing her, got hand on another u3 as well, total of 3 now.

1) Did work for a little while pretty well. then stopped functioning at all. Test different psu, cables, powered hubs etc. Cleaned up inside, still dead. Got a refund from Cryptocrane
2) The other one from Cryptocrane worked, but a bit slow. Faster now with the cgminer 4.8 build from Antminer, might be that one optimizes a bit better than i managed myself. Cleaned it up inside as well, no issues with just this alone now, nearly ever zombies. Directly connected to the pc, usb 2 port.
3) the new addition, reportedly unstable and zombie'ing. Cleaned it up inside, applied new paste etc. Working pretty well, but something wrong with usb recognition. I have to install the winusb driver again if i unplug it, even if back to the same port.

If i start cgminer with both connected, it fails. Starting cgminer, adding one, waiting till it runs, then adding the other, and they seem to be stable for quite a while. Not working with both of them on the same hub.
Zadig freezes if it believes driver install failed (even though it actually installs)

Starting cgminer, adding one, waiting till it runs, then adding the other,

It is the right operation
