Comment 2 for bug 73160

(repeating my comment on bug 73156)

Actually, /dev/wacom is created on startup, by /etc/init.d/wacom-tools. This file is owned by package 'wacom-tools', which *should* be required (or at least recommended) by xserver-xorg-input-wacom.

All this script does is to manually link /dev/wacom to the appropriate device, by grepping for wacom devices on /sys/bus/pnp/devices/*/id .

wacom-tools has a an udev rules file (65-wacom.rules), containing:

KERNEL=="event[0-9]*", SYSFS{idVendor}=="056a", SYMLINK+="input/wacom"

This package (and relevant bits of package 'xorg') was inherited directly from Debian, without Ubuntu specific changes. I'll contact the Debian packager to know if he has any specific reasons on why he decided to do this manually instead of just use /dev/input/wacom and always rely on udev. (does udev works fine with devices attached on the serial port?)
