Looks good here too.

Would you mind doing the same for usbdux.c and usbduxfast.c?
Sure.
As pointed out by Dan, Do you really want the buffer to be of 16 bytes, as we
are using only the first byte and passing the length as '1' in:
usbduxsub_start, usbduxsub_stop, usbduxfastsub_start, usbduxfastsub_stop ?

A buffer size of 1 should be fine.
