Hi Christian,

Can you set the debug level to 8 and post the whole log?  Also, for
timeout issues, having timestamps (via tools/readserial.py tool)
sometimes helps.

Did this regress, or has it never worked?  What type of USB drive are
you attempting to use?

It never worked and tried it with a hand full of different usb sticks.
