Wacom RAW Support
=================

Introduction
------------

This plugin updates integrated Wacom AES and EMR devices. They are typically
connected using I²C and not USB.

GUID Generation
---------------

The HID DeviceInstanceId values are used, e.g. `HIDRAW\VEN_056A&DEV_4875`.

Additionally, for supported AES devices an extra GUID is added for the hardware
ID (e.g. `WACOM\HWID_%04X`) to further disambiguate the panels.

Firmware Format
---------------

The daemon will decompress the cabinet archive and extract a firmware blob in
Intel HEX file format.

This plugin supports the following protocol ID:

 * com.wacom.raw
