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.

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

Quirk use

This plugin uses the following plugin-specific quirks:

Quirk	Description	Minimum fwupd version
`WacomI2cFlashBlockSize`	Block size to transfer firmware	1.2.4
`WacomI2cFlashBaseAddr`	Base address for firmware	1.2.4
`WacomI2cFlashSize`	Maximum size of the firmware zone	1.2.4

Update Behavior

The device usually presents in runtime mode, but on detach re-enumerates with a different HIDRAW PID in a bootloader mode. On attach the device re-enumerates back to the runtime mode.

For this reason the REPLUG_MATCH_GUID internal device flag is used so that the bootloader and runtime modes are treated as the same device.

Vendor ID Security

The vendor ID is set from the udev vendor, in this instance set to HIDRAW:0x056A

External interface access

This plugin requires ioctl HIDIOCSFEATURE access.
