Hi, I am trying to load the module "vivi" which is a virtual video driver (very useful to test applications) Anybody can do it like "modprobe vivi" It creates an additional /dev/videoXX device. The problem is that the permissions of this device are "wrong". If I attach a real USB webcam, the /dev/videoX created has the right permissions. This is what the permissions look like crw-rw---- 1 root root 81, 0 2008-07-12 20:41 /dev/video0 crw-rw---- 1 root root 81, 1 2008-07-12 20:41 /dev/video1 crw-rw---- 1 root root 81, 2 2008-07-12 20:41 /dev/video2 crw-rw----+ 1 root root 81, 3 2008-07-12 20:42 /dev/video3 In this case I did modprobe vivi n_devs=3 (for video0-2) then I plugged in a USB webcam. (for video3) The order does not matter. The difference is the "+" that the real webcam gets. This way a normal user is not allowed to read /dev/video0. I can manually change the permission, but I'd like to avoid the step each time I use it. In udev rules I can only find this rule about videoX (in 50-udev-default.rules) KERNEL=="video0", SYMLINK+="video" Anybody know exactly how it works? How can I debug it?
