Madcatz SE PCB - This device cannot start (Code 10)

Anyone got, and resolved, this error code before?

I’m really annoyed because the PCB was fine 3-4 hrs ago when I first plugged it in to test if it’s working (it was).
Took it into the shed while I put an LS-32 into a shell.
Come back, plugged it in, and now it won’t start in Windows XP (or OSX).

The ONLY other thing I did between then and now was trying to faff around with the drivers from But that shouldn’t have affected the PCB in Windows, right?
