What do you mean ? - SYMLINK+="webcam%n" ? I tried that, didn't help.

The reactived source explains the use of regular expressions in node names:

KERNEL=="fd[0-9]*"

But SYMLINK+="webcam[1-2]*" produced bogus device nodes - unusable. I also 
tried the bracket expression without the wildcard. It looks like udev no 
longer works this way?

One more source [1] explained udev rules with identical usb devices like this:

SUBSYSTEM=="video4linux", SUBSYSTEMS=="usb", KERNELS=="1-1", \ 
SYMLINK+="webcam1"
SUBSYSTEM=="video4linux", SUBSYSTEMS=="usb", KERNELS=="1-2", \ 
SYMLINK+="webcam2"

I changed the usb path to my needs, but this syntax is no longer working?

I tried to force GROUP="video" but didn't help.

Anymore ideas? Should I change the level to sth higher than 10-xxxx.rule?

Is it worth filing a bug report against udev?
