I'm using my S88 MK3 bus powered using the data cable as the power cable. It worked fine for a few months but now it keeps freezing up. The keys will still work but all knobs and screen will freeze. Does this HAVE to be powered with the original power cable? If so, wont it fry the board with the data transfer cable that ALSO carries bus power? I fried one already and thought this was why. I feel lost here.
