I managed to get it to work (using usb-uhci.o) by retransmitting the first 64-byte
packet. In otherwords if I have (say) 'X' bytes to send I send the 1st 64 bytes twice
then I can send the remaining packets as normal.
I have successfully sent upto 16384 bytes from the iPAQ to the PC using this kludge. I
will take a CATC trace with and without the kludge. It looks like some sort of timing
problem.

I use the FILL_BULK_URB macro as per the Programmer's Ref Manual.

Yes. The point I was trying to make was the callback function was never being called if
I sent less or equal to 64 bytes.
