# Hailuck
|
|
|
|
## 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`.
