hi i recently bought 2 block eruptor usb miners online. i plugged them into a dollar store usb hub that doesnt rely on its own power supply (bad idea i know). the lights both turned on and i installed bfgminer. the only way i can mine is to go into cmd.exe and type in
C:\bfgminer\bfgminer.exe -o stratum.bitcoin.cz:3333 -u justinzzz1.worker1 -p UvC3masf+t -G -S all
but when i do tht one of the lights on my miners goes off and then blinks ever so often. the other one has a light on and blinking sometimes. when the bfgminer program appears...it says that only 1 has a hash rate of 292.2 mh/s but the other is at 0? and i dont know if im actually mining or if its just running.. please help
it also shows this
