Do webcams even work on the udoo? I have attempted working with several cameras that i know are uvc compatible and they still do not work. mjpg-streamer gives this error: Code: MJPG Streamer Version: svn rev: i: Using V4L2 device.: /dev/video0 i: Desired Resolution: 640 x 480 i: Frames Per Second.: 5 i: Format............: MJPEG ERROR opening V4L interface: Resource temporarily unavailable Init v4L2 failed !! exit fatal i: init_VideoIn failed and cheese does this when I try to run it from command line.

Will post the rest of the error message when I can copy paste from the udoo. Note: I have attempted this with both debian and the newer ubuntu. Same results. edit: added the full error message. These are also cameras that work on my laptop that runs debian, and on my coworkers mint distro too. This is a UDOO problem.
Previously i try my webcam (vz-wc1688) with vlc and cheese under ubuntu 12. But no luck. Then i change to guvcview. It works....maybe you should try with another player. What your lsusb result?my error maybe because of the image format. My image format is VGA. Maybe u can refer here for more information http://www.ideasonboard.org/uvc/faq/
