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:
