Hi Pratyush,
I tried my "isoc support for gadget zero and usbtest" patches with
the dwc3 driver with the above patch, and the isoc IN tests from
usbtest still didn't work. I discovered that I needed to queue up
8 requests in source_sink_start_ep(), or else the transfer would
stop after the first 4 packets were sent.
Yes exactly, I had also works on the similar line.
Thanks a lot for all these patches. I will apply them and will test.
Yes, its working, atleast for simple cases :)

Many other test of usbtest still does not pass. May be I will work on
them in couple of days.
Do you have the ring expansion patches for the xhci host? Those are
in Linus' current git, they are not in 3.3. Without that, many of the
tests will fail.
Thanks, I will update my kernel. I was using 3.2.1-3.fc16.i686 on my
test PC. :(
Regards
Pratyush
