This document contains instructions on how configure the MCCI Model 3411 USB3.2 Gen2 Test Device https://store.mcci.com/collections/usb-test-devices/products/model-3411. The MCCI device is a multi-mode device. In order to work correctly with USB-IF tools (USB4CV, XHCICV), it must be put into the mode that makes it behave as USB-IF compliance device. In this mode it will work identically to the Microsoft SuperMUTT. If it is not configured correctly, USB-IF tools will fail to identify it as a compliance device.

Verifying MCCI Device Mode
The device will present a different VID/PID, depending which mode it is in. The MCCI device has two modes, a USB-IF compliance device mode and a Loopback device mode. Each mode has its own VID/PID. The VID/PID for the USB-IF compliance device mode is VID=040E, PID=F644 and the VID/PID for the Loopback device mode is VID=040E, PID=F645. Below is a Device summary showing the VID/PID. If USB4CV or XHCICV does not recognize the device, check the VID/PID and make sure it is configured as a USB-IF compliance device.
