So I have two AntMiners USB U2's. I'm currently using CGMiner 3.8.5 because the newest version wasn't working for me. I have a USB hub where I can enable/disable certain hubs. I have both GPU's in there.
For some strange reason, if I have both enabled and start CGMiner only one works and the other fails. Both of them work if I have them being used one at a time. I have tried putting one directly into the USB port of a computer, and one in the USB hub, and it still doesn't work. I can't seem to get both of these working. Here is my start command for the batch file:
cgminer.exe --bmsc-options 115200:20 -o stratum+tcp://uk1.ghash.io:3333 -u MasterBP.1 -p <password> -o stratum+tcp://uk1.ghash.io:3333 -u MasterBP.2 -p <password> --bmsc-freq 0781
pause
Anybody have any solutions or can help me figure this out?
You do realize that GPU stands for graphical processing unit which the antminers are not, right?
Have you tried ditching the hub with switches and plug them in the same hub directly to the computer?
Have you plugged both directly to the computer?
Have you plugged one at the time to the same port on the computer?
What does combiner says at each test?
Sorry I'm still new to mining, so if the terms aren't correct I apologize.
The wierd thing is, when I use cgminer, it will recognize one then the other it will keep spamming errors. Then I will plug in bfgminer and it finds the miner that is getting errors on cgminer. So I can get both working by that method.
CGminer gives off the error:
"See README.txt file included for help
Bitmain detect (1:3) failed to initialise (incorrect device)?"
Thanks for your help so far by the way
