FwupdPlugin – 1.0: Plugin: USI Dock
Description: Reference for FwupdPlugin-1.0: Plugin: USI Dock

## Introduction

This plugin uses the MCU to write all the dock firmware components. The MCU version is provided by the DMC bcdDevice.

This plugin supports the following protocol ID:

- `com.usi.dock`

## GUID Generation

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

- `USB\VID_17EF&PID_7226&REV_0001`
- `USB\VID_17EF&PID_7226`
- `USB\VID_17EF`

Additionally, some extra “component ID” instance IDs are added.

- `USB\VID_17EF&PID_7226&CID_TBT4`
- `USB\VID_17EF&PID_7226&CID_USB3`

## Update Behavior

The device usually presents in runtime mode, but on detach re-enumerates with the same USB PID in an unlocked mode. On attach the device again re-enumerates back to the runtime locked mode.

## Vendor ID Security

The vendor ID is set from the USB vendor.

## External Interface Access

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