Dears,
in linux 2.6.34, we test uvc driver with MJPG-Streamer server via WiFi
network. After about half hour, web cam will hang,
because we can see the error from console:
"uvcvideo: Failed to resubmit video URB (-27)."
after checking code in detail, we find the error is reported from
ehci-sched.c iso_stream_schedule(), the check:
if (unlikely(((start - now) & (mod - 1)) + sched->span>= mod - 2 *
SCHEDULE_SLOP)) {
status = -EFBIG;
goto fail;
}
do you have any idea?
this is generic IPCam testing.
Best Regards,
Soho123
