Udev Rules

If you are updating libwacom to support a new device, the device should also be added to the udev rule to ensure all required properties are set.

When building from source generate an updated ruleset with tools/generate-udev-rules after adding the tablet description files.

When updating an installed version of libwacom, add it manually to the existing ruleset (/lib/udev/rules.d/65-libwacom.rules). Copy a similar device and change the PID to match the PID from the device (for example 0357 below). Obtain the PID from the lsusb command in a terminal.

# Wacom Intuos Pro 2 M 

ENV{ID_BUS}=="usb", ENV{ID_VENDOR_ID}=="056a", ENV{ID_MODEL_ID}=="'''0357'''",  ENV{ID_INPUT}="1", ENV{ID_INPUT_JOYSTICK}="", ENV{ID_INPUT_TABLET}="1"
ATTRS{name}=="* Finger", ENV{ID_BUS}=="usb", ENV{ID_VENDOR_ID}=="056a", ENV{ID_MODEL_ID}=="'''0357'''",  ENV{ID_INPUT_TOUCHPAD}="1"
ATTRS{name}=="* Pad", ENV{ID_BUS}=="usb", ENV{ID_VENDOR_ID}=="056a", ENV{ID_MODEL_ID}=="'''0357'''",  ENV{ID_INPUT_TABLET_PAD}="1"

You can check if your device was added properly in the rules with libwacom-list-local-devices.
