I have a spare AUC cable at home and a Pi - i will test to see if it shows up with no miner when I get off work in a couple hours.
Do you have an ATX PSU you could try to hook up to the miners to see if that worked?
That would be great. Thanks for offering to do this.
I do not have an ATX PSU capable of powering the A741 unfortunately.
Does anyone here recall ever updating the USB drivers on the raspberry pi? I expect the factory firmware/fw downloaded from Canaan would have the correct drivers ahead of time, but figured I'd ask.
Here's the output when I try to manually start cgminer on the Raspberry Pi:
