Ok, I was pointed at ugensa.c, which implements a very dumb serial device
over usb. So I hacked the initialization sequence into it and tried - but
it does not work. (Patch below, of course the call of the init function
needs to depend on the matched device, this was just for testing.)

Guess I'll have to read usbcdc11.pdf now and see what I can make of this
device. Should this go into usbgensa then, or become a different driver?

I'll leave this as ugen for now and examine the device from userland a bit
more.
