History
Richard Hughes 40cd18fa97 Allow using a per-device global percentage completion 
It's actually quite hard to build a front-end for fwupd at the moment
as you're never sure when the progress bar is going to zip back to 0%
and start all over again. Some plugins go 0..100% for write, others
go 0..100% for erase, then again for write, then *again* for verify.

By creating a helper object we can easily split up the progress of the
specific task, e.g. write_firmware().

We can encode at the plugin level "the erase takes 50% of the time, the
write takes 40% and the read takes 10%". This means we can have a
progressbar which goes up just once at a consistent speed.

8BitDo

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

Update Behavior

The device usually presents in runtime mode, but on detach re-enumerates with a different USB VID and PID in a bootloader mode. On attach the device again 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 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

External Interface Access

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