Dear Troy Kisky,
Only perform one copy, either in the bounce
routine for IN transfers, or the debounce
rtn for OUT transfer.
On out transfers, only copy the number
of bytes received from the bounce buffer

Just a question here. Are you sure we never Send AND Reserve the data in one
turn? Because that would need two copyings.
??? s/Reserve/Receive/
As far as I'm aware, a single buffer is only ever used to capture or
provide data not both.
But, if 2 transfers were queued, an OUT and then an IN using the same
buffer, if it worked before
this patch, it should work after as well.
Best regards,
