My 3 x6500 boards won't mine with 3.1.2 on windows, in the UI, it says: "XBS 0: Initializing..."for each device but doesn't program them, along with an error "ft232r_open: Error opening device" three times below in the scrolling text area(sorry can't think of what to call it).
Also, My MMQ goes sick after about 1 minute. BlockEruptors seem fine.
Here is what i get when running bfgminer.exe -D -T -d? -S all
