 Oops yes, my mistake sorry .. I think that really, if somebody were to go
 at this then it would be beneficial to rearrange the methodology such that
 the callback was the last thing to be done and that it could not be called
 before usbd_transfer returned.
 
 I found it a bit strange to see that usbd_transfer can return
 NORMAL_COMPLETION for asynchronous requests (for isoc anyway, I've not
 seen it on a bulk pipe)
