Any idea what "FT_GetComPortNumber(0000000000003D84FF0 (0), 120)" error message in bfgminer is telling me to do? I see the device in device manager (running windows 7x64 btw) on COM120. I get that message when i search for all or specifically probe COM120.
You need to use Zadig on BFx2 to get the WinUSB driver.
Did that and now it doesn't see any devices at all. Ran it with "bfgminer.exe -o stratum+tcp://mint.bitminter.com:3333 -u -p -S bfx:all --bxm-bits=54" and it tells me that "--bxm-bits=54" is an invalid option.
That's because --bxm-bits=54 is an invalid option.
