Hi all,

I have got a problem with usb camera (Microsoft Lifecam VX2000). When I run a openCV it is giving me this error.

libv4l2: error dequeuing buf: invalid argument VIDIOC_DQBUF:invalid argument

on dmesg:

[ 6441.310330] uvcvideo: uvc_dequeue_buffer is timeout!!

When I run it with luvcview it only works at 2-3 fps with default resolution with the following error.

libv4l2: error dequeuing buf:success

Has anyone got any solution for that?
