USB serial:
- bugfix for uvisor driver
- it appears that some UVISOR devices do not
handle when the clear stall command is issued at
the beginning of the initial IN/OUT data transfers.
Reason unknown, probably firmware fault. After patch
stall is only cleared on data transfer errors.
Committed to USB P4, ID=174962 .
