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:
