The Microsoft USB Test Tool (MUTT) is collection of devices for testing interoperability of your USB hardware with the Microsoft USB driver stack. This section provides a brief overview of the different types of MUTT devices, the tests you can run by using the device, and suggests topologies for controller, hub, device, and BIOS/UEFI testing. To communicate with MUTT devices, you need the MUTT software package. This package contains several test tools and drivers that let hardware test engineers test interoperability of their USB controller or hub with the Microsoft USB driver stack. The test tools validate USB host controller software, hardware (including firmware) and any USB hub that is installed between the host controller and the device. | |
Describes various tools you can use to test USB devices and drivers. | |
The USB Type-C Connection Exerciser (USB Type-C ConnEx) hardware board is a custom shield for the Arduino board. The shield provides a four-to-one switch to automate interoperability tests for USB Type-C scenarios. | |
This topic explains how to test the interoperability of USB Type-C enabled systems and Windows. It provides guidelines for device and system manufacturers to perform various functional and stress tests on systems and devices that expose a USB Type-C connector. It assumes that the reader is familiar with the official USB specification and xHCI interoperability test procedures, which can be downloaded from USB.ORG. | |
Before using MUTT devices, you must prepare the test system. | |
Read how to run stress and transfer and SuperMUTT performance tests. Stress and transfer tests are geared towards saturating the bus protocol and the host controller software. These tests perform several simultaneous I/O transfers and cancellations to the MUTT device. The MUTT firmware is programmed to fail transfers during these tests. These failures emulate error conditions that the controller or USB driver stack are exposed to under stressful USB conditions. | |
Describes the Device Fundamental tests that you must run for MUTT devices that are attached to available ports, to perform stress and transfer tests and system power tests. These tests perform simple device transfers at the same time that they perform system power events. Note that devfund tests can only be run on Windows 8. You cannot run stress and transfer tests and the system power tests simultaneously. Perform those tests on separate systems. However, you can switch between stress transfer and system power tests. To do so, complete the first set of tests, reboot the machine, and then follow the instructions of the next test. | |
BIOS/UEFI testing validates USB boot and handoff of the controller to the operating system. | |
The goal of hub testing is to generate a complete set of possible traffic patterns from devices. You can test disconnect scenarios by adding an upstream SuperMUTT Pack. | |
The goal of controller testing is to generate a complete set of possible traffic patterns from hubs and devices. This allows the internal state of controller and its firmware to be fully tested. MUTT devices can help the test by providing an automated method to generate various possible protocol scenarios. | |
The goal of device testing is to test device usage against various hub scenarios and systems power states. The MUTT Pack and SuperMUTT Pack devices can provide a way to expose the device to connect/disconnect scenarios across different hub and system power state scenarios. Test the device when it is attached to a USB 2.0 and 3.0 hubs in the MUTT Pack and SuperMUTT Pack devices, respectively. | |
The Windows Hardware Lab Kit (HLK) tests can be used for additional testing of Systems, USB host controllers, hubs, and devices. These tests cover basic device functionality, reliability, and compatibility with Windows. |

The MUTT Connection Exerciser Type-C (USB Type-C ConnEx) hardware board is a custom shield for the Arduino board. The shield provides a four-to-one switch to automate interoperability tests for USB Type-C scenarios.
This topic provides guidelines to automate the testing of systems, devices, docks with USB Type-C connectors and their interoperability with the Windows operating system. You can test hardware that belong to one of the following categories:
- System: Desktops, laptops, tablets, servers, or phones running a SKU of a version of the Windows operating system with an exposed USB Type-C port.
- Dock: Any USB Type-C device that exposes more than one port.
- Device: Any USB device with a Type-C port that can be attached to a system or dock. This category includes traditional USB devices as well as devices that support the accessory and alternate modes as defined in the USB Type-C specification.
Hardware requirements
To perform the USB Type-C interoperability test procedures by using USB Type-C ConnEx, you need:
System under test (SUT)
Desktops, laptops, tablets, servers, or phones with at least one exposed Type-C USB port.
Arduino Mega 2560 R3
Arduino Mega 2560 R3 is used as the microcontroller for the test setup. This board can be purchased from the Arduino store.
Power adapter for the microcontroller.
For information about compatible adapters for the Arduino Mega 2560 R3 board, see this site.
USB Type-C ConnEx
The shield has one male USB Type-C port (labeled J1) to which the SUT is connected. The shield also has four other USB ports (labeled J2, J3, J4, J6) to which devices can be attached that act as peripherals to the SUT. The shield monitors amperage and voltage being drawn from the SUT. You can buy this board from MCCI or JJG Technologies.
USB A-to-B cable
You will use this cable to connect a PC to the microcontroller in order to update the firmware on the microcontroller to run tests.
Peripheral USB devices
Any USB device with a USB Type-C port that can be attached to the SUT. This category includes traditional USB devices and other devices that support the accessory and alternate modes as defined in the USB Type-C specification.
USB charger
USB Type-C that supports USB Type-C current requirements and optionally USB Power Delivery. You also need a USB Micro-B charger for J6.
Proxy controller
The USB Type-C ConnEx can be controlled by using a proxy for running the tests. The proxy controller can be one of these entities:
Secondary desktop PC or a laptop.
The proxy controller communicates, with a mobile SUT; the microcontroller to load the firmware.
SUT by using a secondary USB port.
SUT by using a 3.5mm audio jack.
In this set up, you need:
DTMF shield to run tests on SUTs with a single USB Type-C port. DTMF provides the ability to control the shield from a single-port device with an audio jack after the initial flash of the firmware has been completed.
4-pin male-to-male audio cable used to connect the DTMF shield to the SUT. This allows the SUT to control the USB Type-C shield during testing.
Software requirements
Make sure you meet these requirements:
Your SUT must have the version of the Windows operating system with which you want to test interoperability.
The proxy controller must be running Windows 10.
and install the latest MUTT software package on the proxy controller.The package is a suite of tools used to run tests with USB Type-C ConnEx. It includes utilities to update the firmware, switch between the peripheral ports, and send requests to simulate test cases. It also contains test driver packages that test the functionality of the buses, its controller, and devices connected to the bus.
For UCSI based systems we strongly recommended testing with some additional settings to help discover UCSI firmware bugs. This setting will make UCSI firmware issues discoverable and is highly recommended for testing purposes only. Please see “Converting firmware failures to bugchecks” in this blog post.
Installation of the test tools requires an elevated command window.
To open an elevated command window, the user must be a member of the Administrators group on the proxy controller. To open an elevated Command Prompt window, create a desktop shortcut to Cmd.exe, right-click the Cmd.exe shortcut, and select Run as administrator.

Follow this procedure to set up your test environment.
The configuration should be similar to this image. Note that the USB Type-C port on the microcontroller provides control over USB Type-C ConnEx when connected to a PC.
In these steps, you will connect the hardware pieces, update the firmware on the microcontroller, and validate the installation. The DTMF shield provides control over USB Type-C ConnEx when connected to the audio port of a phone or tablet.
Connect the microcontroller to the USB Type-C shield.
If the USB Type-C ConnEx did not come assembled, then continue with step 1. If your USB Type-C ConnEx has been assembled, then proceed to step 2.
Caution This step must be performed carefully because the pins bend easily.
Align the pins of the USB Type-C shield with the receptors on the microcontroller by making sure that the boards are level to each other.
Gently press the two boards together. Be careful not to bend the pins on the shield.
Your assembled unit should be similar to this image:

Right-click the Start button in the task bar and select Device Manager.
Expand the Ports (COM & LPT) node and note the COM port that is used by the microcontroller. In this example, it is connected to COM 4.
ConnExUtil.exe
Here are the command line options that ConnExUtil.exe supports for controlling the USB Type-C ConnEx board.
| Use case | Option | Description |
|---|---|---|
| Device Discovery List all devices connected to USB Type-C ConnEx | /list | For USB connected devices, this option lists the device instance path. For audio connected devices it shows Audio. To view audio devices, use this in combination with the /all parameter. Lists with 1-based index that can be used for input to the /# parameter. |
| Device Selection Select all devices connected to USB Type-C ConnEx, including audio. | /all | Optional. Without this parameter, the utility addresses USB connected devices. Use this parameter only if an audio connected device is in use. Audio discovery is time consuming and disabled by default. |
| Device Selection Select a specific device connected to USB Type-C ConnEx ‘n’. | /#n | (Optional) Input n is a 1-based index of the available devices connected to USB Type-C ConnEx which can be viewed by using the /list parameter. Without this parameter, the default behavior is to run each command on all USB Type-C ConnEx boards. |
| Device Command | /setPortp | Switch to the specified port p. Connect a port either by specifying number (1 – 4) or by name (J2, J3, J4, J6). 0 disconnects all ports. |
| Device Command | /getPort | Read the currently connected port. |
| Device Command Read amperage/voltage information | /volts /amps /version | Read the current voltage. Read the current amperage. Read the device version. |
| Device Command Enable SuperSpeed | /SuperSpeedOn | Enables SuperSpeed globally for current and future connections until a /SuperSpeedOff command is sent. SuperSpeed is enabled by default. If SuperSpeed is disabled, and port 1 or 2 is connected, this command triggers a reconnect at SuperSpeed. |
| Device Command Disable SuperSpeed | /SuperSpeedOff | Disables SuperSpeed globally for current and future connections until a /SuperSpeedOn command is sent or the device is reset. If SuperSpeed is enabled and port 1 or 2 is connected, this command triggers a reconnect with SuperSpeed lines disabled. |
Set command delay | /setDelayt | Sets command delay t in seconds. Setting a command delay will cause the next /setPort or /SuperSpeed{On/Off} command to be delayed by t seconds where t ranges from 0 to 99. This is a one-time setting, only the next command is delayed. Sending multiple commands before the delay timer has expired is not supported. |
Set disconnect timeout in milliseconds | /setDisconnectTimeoutt | Set a disconnect timeout for the next non-zero /setPort command. On the next connect event, the port will only remain connected for t milliseconds before disconnecting. This is a one-time setting, only the next connect event will be automatically disconnected. Allowed range is from 0 – 9999 ms. |
Batch Command: Output power measurements to a .csv file. | /powercsv | Append the current power measurements and timestamp into power.csv The first run creates power.csv. On subsequent runs appends data to this file. Rename or delete the file to start fresh data capture. Each run appends a line with the following format: <index>,<time>,<volts>,<amps>. index is the device index given by /list, so multiple devices may be monitored simultaneously. time is the raw timestamp in seconds. volts and amps are recorded to two decimal places. This data may be captured over long periods of time and plotted in a spreadsheet application, see the cxpower.cmd script. |
Batch Command: Run unit test of major functionality | /test | Tests all the major functionality of the device. Use for basic validation of the functionality of the device. If this command fails, please power cycle the device and update the firmware. |
Batch Command: Basic demo of the port switching sequence. | /demo d | Loop through all ports one time, with d second delay on each port Writes the port number, volts and amps on each port into demoresult.txt. |
Sample Commands
Connect to a port
Alternatively use the port name as printed on the board:
Disconnect all ports
Loop through all ports
Scripts for controlling the USB Type-C ConnEx board
These scripts exercise the control interface supported by ConnExUtil.exe to run sequential and stress type tests with the USB Type-C ConnEx through the command line. All of these scripts support the optional command line parameter audio to indicate that the USB Type-C ConnEx board is connected over the 3.5 mm audio interface. By default they will only attempt to use USB connected boards.
Simple connect / disconnect sequence: CXLOOP.CMD
Connects and disconnects the SUT to and from each port (1-4) and pauses on each port prompting the tester to validate the connection on that port.
Random connect / disconnect loop: CXSTRESS.CMD
Connects and disconnects the SUT to and from each port at random for a random interval of 0.0-5.0 seconds in an infinite loop. When connecting to the USB Type-C ports it will randomly enable or disable SuperSpeed connection on that port, and will randomly instruct the board to disconnect quickly on that port at some random interval 0 – 999 ms.
The command line parameter C causes the script to only switch between the USB Type-C ports and the disconnected state. A numeric command line parameter resets the maximum random interval between switches from the default of 5.0 seconds to the input value in seconds. Parameters may be passed in any order.
Long running power measurement: CXPOWER.CMD
Saves the amperage and voltage reported by the USB Type-C ConnEx to output file power.csv at 2 second intervals. The data is formatted as comma-separated variables as follows:
index,time,volts,amps
index is the device index given by the ConnExUtil.exe /list command so multiple devices may be monitored simultaneously.
time is the raw timestamp in seconds.
volts and amps are recorded to 2 decimal places.
After capture is complete, this data may be post processed into charts showing power consumption over time, for example the power consumption for the duration of a battery charge cycle. A numeric command line parameter resets the default measurement interval of 2 seconds to the input value in seconds.
About test cases
The USB Type-C interoperability test procedures are divided into two sections: functional testing (FT) and stress testing (ST). Each test section describes the test case and identifies the category that applies to the test. The product must be tested against the entire applicable category. Certain test cases contain links to relevant hints and tips for additional information. This section is focused on USB Type-C functionality and experience. A USB Type-C solution may contains other USB components such as a USB hub or USB controller. Detailed testing of USB hubs and controllers is covered in both the USB-IF's xHCI interoperability test procedures and the Windows Hardware Certification Kit.
These test cases are based on the ConnExUtil commands and example scripts Scripts for controlling the USB Type-C ConnEx board. The test cases refer to the scripts. Customize the scripts as required for your test scenario.
Device Enumeration
Confirms that core aspects of device enumeration are functional.
Alternate Mode Negotiation
