History
Richard Hughes c4b7f42e43 Only compress one version of the builtin-quirks 
Saving the quirks in the GResource section worked well, but it made the build
system very complicated and also meant the .data section was duplicated in
both `fwupd` and `fwupdtool` -- negating a lot of the hard-fought savings.

Simplify this feature so that we just `cat` all the quirk files together, then
gzip them into a single file. This means that at startup fwupd only needs to
check the mtime of one file, and weirdly it's actually faster to load a smaller
compressed file from disk that it is to load multiple uncompressed files.

Thelio IO

Introduction

This plugin is used to detach the Thelio IO device to DFU mode.

To switch to this mode 1 has to be written to the bootloader file in sysfs.

GUID Generation

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

  • USB\VID_1209&PID_1776&REV_0001

Update Behavior

The device usually presents in runtime mode, but on detach re-enumerates with a different USB VID and PID in DFU mode. The device is then handled by the dfu plugin.

On DFU 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, in this instance set to USB:0x1209

External Interface Access

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