In that case, debug time.
Usual problems are bad routing of the tracks on the board , so try with USB 1.1 hub and if that works, that's your problem.
Another suggestion would be to try the 100MB transfer in Linux and see if this works or not.
That would help us to narrow down whether this is a hardware or software problem.
Thank you Marek and Fabio for your input!
I tried the file transfer in Linux and this seems to work fine. Also we have been using this hardware for quite some time, also with USB mass storage and large files in Linux and I can't remember any problems. For these reasons I think that the hardware is ok.
I added the DEBUG defines and here are the lines around one of the timeouts. With my very limited knowledge of how usb works, I can't read much from those messages:
