Splitting hairs here, but that's CGminer 3.12.3, and I seen Marto's screen shot (a couple of posts up) with version 4.0.0.

This is new version still in tests
A fast question, there is any solution for that the hex16a2 mini USB power dont give backward 5volt ? When i cut the usb cable red and black cables, then the board dont work.
Thanks.
Wierd, when I taped out the outer pins on my troublesome Hex16B board's cable, it worked fine.
(also work on Hex8A1, but it was something else that was the problem, needed a fan on the 5v PSU line, to help regulate the PSU.)
Are you sure you didn't damage the data cables? If you are, try adding back the ground. If that don't work you could try +5v and ground powered from a 5v PSU line (Red/Black), with more Amps in the PSU it shouldn't flow back, and PSU is designed to handle bad loads if it did.
