History
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.

Fresco PD

Introduction

This plugin is used to update Power Devlivery devices by Fresco.

Firmware Format

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

This plugin supports the following protocol ID:

  • com.frescologic.pd

GUID Generation

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

  • USB\VID_1D5C&PID_7102&REV_0001
  • USB\VID_1D5C&PID_7102
  • USB\VID_1D5C

These devices also use custom GUID values, e.g.

  • USB\VID_1D5C&PID_7102&CID_01

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:0x1D5C

External Interface Access

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