Yes, it could be one (at least I've also guessed this - I could still be 
completely wrong). But the problem is now to find a good starting point for 
the debugging effort.

I've only looked at Simon's screen once while he gather USB dumps but didn't 
spot any obvious at that time. There was also the problem that the comparison 
dump looked already a lot different due to some timing differences.

I think Simon can give you later more details (when required).

Kind regards,
