Nice catch, I'll add it into the stack of fixes that need to be made in V8. 
Though I'd rather rebase V8 on top of usb-next.

btw. this supports both host and gadget mode (not OTG right now), certainly 
handling the fact the gadget code isn't present in kernel needs to be done. In 
the meantime, enable also gadget mode and add ci13xxx-mxs into the kernel, it 
should fix your problem.

Thanks for the report!
