Bc2000 (for the BCF2000 & BCR2000)

Just picked one of these up 2nd hand (actually my second BCR). When I plugged it in/installed drives, it obviously detected it because it let me install the driver but then pops up a windows error

"The I/O device has reported and I/O error"

Obviously i tried wiping the drivers, and restarting, and all that. Possibly a bad USB cable but I don't have another to try.

Tried it on 3 different computers - all do the same.

Will not detect in BCManager. Can't control via USB (soft synths/learning etc).

Any clues on this problem? Or is it a damaged logic chip or something?

Previous owner says it worked ok (on mac) via USB. I did the Panic reset a few times but that's mainly for midi anyway isn't ? It works Fine over midi btw (to my hardware synths)

thanks
