Richard Hughes cddf5b5b89 Only auto-add counterpart GUIDs when required
Doing this unconditionally means we accidentally 'bleed' one device mode into
another in a non-obvious way. For instance, a device might have two operating
modes with different GUIDs. If firmware is supplied for both modes in the same
cabinet archive then we might accidentally match the 'wrong' firmware when
the daemon has observed a mode switch and added the counterpart GUIDs.

We only really need the counterpart GUIDs when switching between Jabra, 8bitdo
and DFU devices where the DFU bootloader VID:PID is not manually tagged with
`CounterpartGuid` in a quirk file. In the general case lets keep it simple to
avoid difficult to find bugs.

8Bitdo Support

Introduction

This plugin can flash the firmware on the 8Bitdo game pads.

Ebitdo support is supported directly by this project with the embedded libebitdo library and is possible thanks to the vendor open sourcing the flashing tool.

The 8Bitdo devices share legacy USB VID/PIDs with other projects and so we have to be a bit careful to not claim other devices as our own.

Firmware Format

The daemon will decompress the cabinet archive and extract a firmware blob in an unspecified binary file format. The binary file has a vendor-specific header that is used when flashing the image.

This plugin supports the following protocol ID:

  • com.8bitdo

GUID Generation

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

  • USB\VID_2DC8&PID_AB11&REV_0001
  • USB\VID_2DC8&PID_AB11
  • USB\VID_2DC8

Vendor ID Security

The vendor ID is set from the USB vendor, which is set to various different values depending on the model and device mode. The list of USB VIDs used is:

  • USB:0x2DC8
  • USB:0x0483
  • USB:0x1002
  • USB:0x1235
  • USB:0x2002
  • USB:0x8000
