## GUID Generation
The plugin uses a custom DeviceInstanceId value derived from the device name
provided by system firmware and read from sysfs, such as:
Devices use an extra instance ID derived from SMBIOS, e.g.
* `PARADE-LSPCON\NAME_1AF80175:00`
* `PARADE-LSPCON\NAME_1AF80175:00&FAMILY_Google_Hatch`
