# 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`.
