  Send the next packet to the USB. The first packet gets sent by directly

  call the interrupt mechanism will keep things going.
 
  We return the actual number of bytes we've queued to the UDC. Note that
  until the next interrupt we wont know if it has been transmitted. We'll
  deal with the failure by saving the original packet and retransmitting if
  we get an error. In that case we'll return 0 as the number of bytes sent
  since no new bytes have been consumed from the caller's buffer.
 
  When the packet is accepted we return the number of bytes and grab the 
  next packet (or portion thereof).
