Richard Hughes e87fc05ab9 Speed up the daemon startup by ~2% by doing dlsym much less 
We were calling g_module_symbol() 2703 times, which is actually more
expensive than you'd think.

It also means the plugins are actually what we tell people they are:
A set of vfuncs that get run. The reality before that they were dlsym'd
functions that get called at pretty random times.

PixArt RF Devices

Introduction

This plugin allows the user to update any supported Pixart RF Device using a custom HID-based OTA protocol

Firmware Format

The daemon will decompress the cabinet archive and extract a firmware blob in an unspecified binary file format.

This plugin supports the following protocol ID:

  • com.pixart.rf

GUID Generation

These devices use the standard HIDRAW DeviceInstanceId values for both Pixart Imaging, Inc and Primax Electronics, Ltd, e.g.

  • HIDRAW\VEN_093A&DEV_2801
  • HIDRAW\VEN_0461&DEV_4EEF
  • HIDRAW\VEN_0461&DEV_4EEF&NAME_${NAME}
  • HIDRAW\VEN_0461&DEV_4EEF&MODEL_${MODEL_NAME}

Additionally, a custom GUID values including the name is used, e.g.

Update Behavior

The 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:0x093A

External Interface Access

This plugin requires ioctl HIDIOCSFEATURE and HIDIOCGFEATURE access.
