Plugin: OptionROM


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

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)

Version Considerations

This plugin has been available since fwupd version 1.3.3.
