Great. So it's ok for Sascha to add

to the commit log?

Yes. We have also tested the V2 of this patch, submitted earlier today, and it functions correctly.

If one receives timeouts on the host computer, try setting 
usbcore.autosuspend=-1.
Did you need this kernel parameter with the old dfu command as well?
If only new dfu command makes this parameter necessary, we might need to look
why the timing behavior changed.

Yes, it was also required before this patch. We have tested it with a couple of hosts and this issue was only present on one machine.

Cheers,
Ahmad
