UDev Support

Introduction

This plugin reads the version numbers of PCI devices. It cannot deploy firmware onto devices but is used to list devices with known firmware updates that may require booting into another operating system to apply.

This plugin is also able to read and parse the firmware of some PCI devices which allows some host state verification to be done.

GUID Generation

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

  • PCI\VEN_%04X&DEV_%04X

Additionally, GUIDs found in OptionROMs may also be added.
