Did you try the defect one alone? What USB hub are you using? In what position is the potentiometer for the voltage adjustment? It´s located in the lower right edge with sight on the non heatsink side and USB port at the bottom. There is a flat edge on the pot. Try turning it to 3 o´clock.
thank you for the reply!
yes i tried the defect alone. nothing.
not using a hub. (yet) i have usb 3.0 ports. the fact that one works and one doesnt shouldnt be an issue with the power output. (I think, probably wrong.) yes ive also swapped them in the same port. the one that works, works on all the 3.0 ports. the defunct gets detected by zadig, and control panel, but doesn't get picked up by cgminer alone or together.
i will try turning the screw. I had an idea to mess with it. but i dont know what im doing. im a noob. im learning. im hoping to setup a large rig in the future. this is all a learning experience for me at the moment.
