         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 .
