Plugin: USI Dock


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

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

  • USB\VID_17EF&PID_7226&CID_USB3
  • USB\VID_17EF&PID_7226&CID_40B0&DMCVER_10.10

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.
