Dear everyone:
I wonder why v4l2 driver cancel all the urbs in VIDIOC_S_FMT and
then reinit all the urbs to submit.
VIDIOC_S_FMT only negotiate frame format with application like
mplayer and has nothing to do with our v4l2 driver.
And in my driver I follow the way most drivers have taken, but
when I use usb_submit_urb() in VIDIOC_S_FMT to submit all the urbs
successfully reinited, my Ubuntu crashes. Caps and Scroll flash during
my Ubuntu crashes. I can't get any value message from my syslog.
Could somebody help me with this issue?
Thank you in advance!
