Hi Dave,
After the stress test and backport gadget code from
2.6.24 to my current 2.6.20 version, the problem
remains .
It always reports error when responding to the
following setup request:
SETUP 80.06 v0300 i0000 l00ff
usb.c always fails at replying to this request, it
reports:
write string data: Device or resource busy
ep0 read after poll: Level 2 halted
I don't know if AIO is mandantory for this
enumaration, as I did not use AIO.
I also got something DEBUG message from gadgetfs as
the following:
SETUP 80.06 v0300 i0000 l00ff
gadgetfs: delegate req80.06 v0300 i0000 l255
gadgetfs: event[1] = 3
gadgetfs: ep0 request busy!
gadgetfs: ep0in stall
Any suggestion for me?
Thanks ...
