It is far too easy to forget to set FWUPD_DEVICE_FLAG_NO_GUID_MATCHING for new
plugins, and without it it all works really well *until* a user has two devices
of the same type installed at the same time and then one 'disappears' for hard
to explain reasons. Typically we only need it for replug anyway!
Explicitly opt-in to this rarely-required behaviour, with the default to just
use the physical and logical IDs. Also document the update behavior for each
plugin to explain why the flag is being used.
This allows you to have two identical Unifying plugged in without one of them
being hidden from the user, at the same time allowing a HIDRAW<->USB transition
when going to and from bootloader and runtime modes.
This removes the workaround added in 99eb3f06b6.

Hailuck Support
|
|
===============
|
|
|
|
Introduction
|
|
------------
|
|
|
|
Hailuck produce the firmware used on the keyboard and trackpad used in the
|
|
Pinebook Pro laptops.
|
|
|
|
Firmware Format
|
|
---------------
|
|
|
|
The daemon will decompress the cabinet archive and extract a firmware blob in
|
|
a packed binary file format.
|
|
|
|
This plugin supports the following protocol ID:
|
|
|
|
* com.hailuck.kbd
|
|
* com.hailuck.tp
|
|
|
|
GUID Generation
|
|
---------------
|
|
|
|
These devices use the standard USB DeviceInstanceId values, e.g.
|
|
|
|
* `USB\VID_0603&PID_1020`
|
|
|
|
Update Behavior
|
|
---------------
|
|
|
|
The keyboard device usually presents in runtime mode, but on detach it
|
|
re-enumerates with a different USB VID and PID in 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.
|
|
|
|
The touchpad firmware is deployed when the device is in normal runtime mode,
|
|
and the device will reset when the new firmware has been written.
|
|
|
|
Vendor ID Security
|
|
------------------
|
|
|
|
The vendor ID is set from the USB vendor, in this instance set to `USB:0x0603`
|
|
|
|
External interface access
|
|
-------------------------
|
|
This plugin requires read/write access to `/dev/bus/usb`.
