"Auto" mode merely means that the packet will be sent as soon as there
are enough bytes in the FIFO.  However, someone, somewhere still has to
put bytes in the FIFO.  I don't see that you are doing that.  If you
want to do loopback, then you have to have FX2 code that copies from the
endpoint 2 FIFO into the endpoint 6 FIFO.

Remember that only certain registers need the SYNCDELAY.  The list is
long, but it does not include every register.
