Ok - can you play around with these commands and add them to the MIDI driver? The stubs are all there now, and I think all that's missing is the termios call and maybe write_latency_timer(). I could prepare another patch, but I think it's faster if you just try around which command sequence helps :)

I have tried to replicate the control messages to the best of my ability, but I'm still getting no MIDI events. The actual values in the stream may still be wrong (as per Clemens' email), so is there anywhere I can hook into to see if I get any USB activity *at all*?
