Radek, Please attach the full dmesg output when starting video capture with the second camera. Also increase log verbosity first: something like this: rmmod uvcvideo modprobe uvcvideo trace=65535 You should also refer your capture settings (if I remember MJPG 640x480@24 fps) and that if you use one c910 and one c600 everything works fine. Note: Cc linux-media since you also posted this thread there.
