Hi everyone,
I'm posting here cause I think my problem is related to cgminer.
Indeed, I bought an old antminer U3 for bitcoin mining (just as a hobby). I had followed all the procedures with the CP210x driver and Zadig. I had disable all the firewall and antivirus/antimalware software.
Windows can detect the device with the right driver.
But cg miner keep displaying "USB init, open device failed, err -12".
I'm joining to this post some screenshots.
I really think the problem is coming from cgminer and the device.
I'm using windows 10, 64bit. I tried with cgminer 4.10, 4.9 and 4.8.
The command line for the batch is simple :
cgminer.exe -o stratum+tcp://stratum.slushpool.com:3333 -u hurtol.worker1 -p Password --au3-volt 810 --au3-freq 250
pause
And the screenshot :

Thank you very much for your help !
