but motion and uvccapture complained that they can't find /dev/video0 even if  I created the node:
mknod /dev/video0 c 81 0 

Device can be found preloading v4l2convert
 LD_PRELOAD=/usr/lib/arm-linux-gnueabihf/libv4l/v4l2convert.so motion [options here]

Had to install v4l-utils first

sudo apt-get install v4l-utils
