Is there anyway to disable a specific type of hardware unit? I have either Antminer U2s that I don't want CGMiner controlling but I want it to control my RockMiner New R-Box.
Look thru the readme files or news files. Should find the -S noauto (not sure of the exact dash part) then you will look for the correct argument for telling cgminer to use the port and hub location of the device(s) you want it to use. Be aware, zadig and silabs drivers don't play nice with each other on the same machine, as well as the possibility that the port/hub assignments may change when you disconnect/restart the pc.
