OK, picked and pushed. I think panto picked it up as well tho, but maybe I 
unleashed too much mental terror unto him with my OvisLink WL-1100SD that he is 
paralyzed by it ;-) Panto, I will pick this patch, OK ?

As for the DFU, what do we do about the PRs ? DFU is part of USB, so I shall 
logically pick the PRs from you and move them to trini, but if you're unhappy 
about this, we need to talk about that. Tom, Lukasz ... thoughts ?
