Wacom USB

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+ license.

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 their 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

Update Behavior

The firmware is deployed when the device is in normal runtime mode, and the device will reset when the new firmware has been written.

Vendor ID Security

The vendor ID is set from the USB vendor, for example set to USB:0x056A

External Interface Access

This plugin requires read/write access to /dev/bus/usb.
