I have tested too, and I cannot see rather a real improvement. Sometimes
it hangs after the first attempt, sometimes I need some time (but as
Wolfgang reports, only a few..) to get into trouble.

I can confirm Heiko's test and the board works flawlessy flushing the
cache inside the handshake() routine. Howeever, it seems this solves
issue with usb, but maybe we get the same strange behavior with another
driver...

Best regards,
Stefano
