Aha! That explains why it compiles, and probably also
explains why it doesn't actually work ;-) . I simply
corrected a few obvious errors, without trying to
understand the code properly. The chances of that being
enough to fix it were bound to be pretty small.
I'd like to try dwc2 as John suggests and maybe AA
dwc-usb as well, but it might be a while because
I don't know much about USB and don't have a lot of
time at the moment either. I'll post again if I do
get anywhere and hope to hear from you if you do too.
