 Oops, it seems that this patch also does not work as expected: after some time
of playing with flash card and working with the system it started to stall
as unpatched system, but it freezes the system -- even IP stack was frozen (I
am using DEVICE_POLLING), so I were to remove the flash from the port -- system
was unfrozen and continued to work. So something is still bad with the USB.
 I'll try to do some long testing with USB 1.1 -- maybe it will show the same
behaviour after some more time.
