Hi Ben,
of course I used your fixes to compile the code!
Maybe you would be more lucky with the AA's dwc-usb module and should
give it a try? Actually I'm not very experienced with kernel hacking so
I can not really give you a qualified hint.
Probably I will also try to use dwc-usb one with my device as this one
seems to be the most promising one.
