Richard Hughes a78b13fb71 Use a different Device ID for the OptionROM devices 
We want to continue to dedupe the ID, and the priority should be decided on the
GUID match.

OptionROM 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.

Vendor ID Security

The device is not upgradable and thus requires no vendor ID set.

External interface access

This plugin requires read access to the rom file of PCI devices (/sys/class/pci_bus/*/device/rom)
