Description Diederik van der Boor 2004-07-27 03:34:29 UTC 
The configuration of udev currently states that v4l devices appear in /dev/v4l/video#. I would love to have a symlink to /dev/video# by default, since many v4l applications only look at that place. (in fact, I already assumed the webcam driver didn't work)

Thanks in advice.

Reproducible: Always

Yes, this is very annoying, everytime I reload one driver, I have to recreate the device. I reload this driver often, because it's under heavy development.

Now I'm not sure whose fault it is. One could also argue that the driver(s) look at the wrong spot. Can someone shine a light on this issue? Because if it's a driver issue, we need to make bugreports there, not here...
Thanx

Very simple fix.  In /etc/udev/rules.d/50-udev.rules change this line:

KERNEL="video[0-9]*", NAME="v4l/video%n"

To this:

KERNEL="video[0-9]*", NAME="v4l/video%n", SYMLINK="video%n"

Works for me.

Will be fixed in the next release of udev.
