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. -- rea
