I am not even sure if I am posting this in the correct place as I have no idea what actually is the problem.
I got my Antminer U2's out of storage to sell a few to a friend who was wanting to collect old asic miners. Out of the 11 I have only 4 show up as show up as ANU. The other 9 show up as AU3, which of course just throws errors. I am running cgminer 4.11.1 on Raspberry Pi 4.
I have changed usb hubs, deleted cgminer.conf, rebuilt cgminer and they still show up as AU3.
I remember using --usb ICA:0 in the past to disable block erupters in the past. It has been so long since I have used these. I remember using --usb ICA:0 to run two instances of cgminer, one for Blue Furry and one with the antminers.
I know --usb AU3 does not work. Anyone know how I can keep them from being detected as U3?
