This is a resend of this patch, I previously sent an email on 3/27 but got no
response. James Kung pointed out this bug to me.
The -1 appears to be a bug that prevents checking the last fully used uframe for
a split isoc transfer. The code currently does not check the last fully used
uframe of a multi-uframe fullspeed isoc transfer. This patch changes it to
check each fully used uframe of a multi-uframe fullspeed isoc transfer.
David, Greg, I believe this patch should be applied, do you agree?
