Richard Hughes eddaed0c11 Allow specifying more than one VendorID for a device 
Asking the user for the UID mapping isn't working very well, as it requires lots
of manual handholding. It also doesn't work very well when the device vendor
does not actually have a PCI ID or if the vendor has split into two entities.

Just use the OUI address as an additional VendorID and match any of the device
IDs against any of the metadata-supplied values.

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+ 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

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.
