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

This plugin supports the following protocol ID:

## GUID Generation

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

- `USB\VID_046D&PID_089B`
- `USB\VID_046D&PID_08D3`

## Quirk Use

This plugin uses the following plugin-specific quirks:

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