You use udev rules to give persistent names.
Here is my /etc/udev/rules.d/video.rules file,
which creates /dev/webcam and /dev/tvtuner as appropriate.
KERNEL=="video*" SYSFS{name}=="USB2.0 Camera", NAME="video%n", SYMLINK+="webcam"
KERNEL=="video*" SYSFS{name}=="em28xx*", NAME="video%n", SYMLINK+="tvtuner"
To find distinguishing attributes to match on use:
echo /sys/class/video4linux/video* | xargs -n1 udevinfo -a -p
cheers,
Pádraig.
