 Committed with some modifications:
 
 1) control transfers automatically clear-stall.
 2) control transfers should have a timeout
 3) flowcontrol[2,3] must be zeroed
 4) flowcontrol must be stored in little endian format
 5) reduce the interval a little bit, because it is blocking other control 
 transfers to this device.
 6) reduce control transfer buffer to the request plus 8 bytes, of which only 1 
 byte is used.
 
 Please verify and check that my modifications to your patch are correct:

 Thanks for the patch!
