There are several typos here and there...
First, s/Pedning/pending/ in the subject.
Ohh.. I will correct all these while sending V2.
I am doing some more test with other gadgets and then will send V2.
If xfernotready is received and there is no request in request_list then
PENDING flag must be set, so that next request in ep queue is executed.
In case of isoc transfer, if xfornotready is alreday elapsed and even first
s/xfornotready/xfernotready/, s/alreday/already/.
request has not been queued to request_list, then issue END TRANSFER, so that
you can receive xfernotready again and can have notion of current microframe.
