Wacom USB Support

Introduction

Wacom provides interactive pen displays, pen tablets, and styluses to equip and inspire everyone make the world a more creative place.

From 2016 Wacom has been using a HID-based proprietary flashing algorithm which has been documented by support team at Wacom and provided under NDA under the understanding it would be used to build a plugin under a LGPLv2+ licence.

Wacom devices are actually composite devices, with the main ARM CPU being programmed using a more complicated erase, write, verify algorithm based on a historical update protocol. The "sub-module" devices use a newer protocol, again based on HID, but are handled differently depending on thier type.

Firmware Format

The daemon will decompress the cabinet archive and extract a firmware blob in the following formats:

  • Touch module: Intel HEX file format
  • Bluetooth module: Unknown airoflash file format
  • EMR module: Plain SREC file format
  • Main module: SREC file format, with a custom WACOM vendor header

This plugin supports the following protocol ID:

  • com.wacom.usb

GUID Generation

These devices use the standard USB DeviceInstanceId values, e.g.

  • USB\VID_056A&PID_0378&REV_0001
  • USB\VID_056A&PID_0378
  • USB\VID_056A
