USB Power Delivery Fast Role Swap (FRS) Switch

The USB Power Delivery Fast Role Swap switches provide a tool to simulate a loss of external power. They are currently available to use for correlation, validation and debugging of USB Fast Role Swap architecture. Please note these are not to be used for USB-IF certification purposes at this time.

The switches support up to 20 volts at up to 10A of current designed to work at full functionality from between 0 to 40 degrees Celsius. The switches should not be loaded for an extended period.

When connecting or disconnecting the DC side spliced power line to the FRS Switch via the banana plug connectors, users *MUST* disconnect the AC/DC power adapter from AC power and ensure all residual power in the AC/DC adapter is discharged.

The USB PD FRS Switch is available to USB-IF members at the E-Store located at https://www.usb.org/estore. Please find the User Guide here.

 

USB4® Test Tools

USB4 Host Power Management in Windows

Some USB4 hosts require that power management of the USB4 domain be disabled during testing.  This setting can be changed in Device Manager via the “Power Management” tab on the host router.  If this tab Is not available, download a batch file here.  Run it with administrator permissions and reboot the system.  This will also enable testsigning for the system, so the system might need to have Secure Boot disabled.


It is recommended that USB4 hosts have this power management disabled for USB4 Electrical Testing and and USB4 tunneled USB 3.2 Link Layer Testing that uses the Microsoft CM.  Email usbcompliance@usb.org with any questions about this.

You must re-enable USB4 power management for the remainder of USB4 certification testing.

USB4CV Tool

This tool is used to test the Logical Layer, Protocol Layer, and Tunneling functionality of a USB4 Router. This tool takes control over the USB4 Connection Manager and renders all products connected to it unusable. USB4CV should not be installed on an oscilloscope or any system that uses USB as its only form of input from the user.

Some USB4CV Chapter 9 tests require the use of the MCCI Compliance device. More information can be found here.

The USB4CV tool Ver. 1.3.2.0 (August 29, 2024) is available below.  It supports both x64 and ARM64 architecture.

NOTE 1: In order to use USB4CV, User Account Control (UAC) must be turned off. After turning off UAC, the system must be rebooted.
NOTE 2: The USB4CV tool is supported on Windows 10 and above.  

If you have questions please email techadmin@usb.org.

For vendors seeking version numbers to be used at upcoming workshops please visit the compliance updates page found here.

Products Used for Testing

Known Good Products and Interoperability Products

KGD and KGH Used For Certification Testing
The USB-IF Compliance program uses specific USB devices and USB hubs during certification testing. Email ssusbcompliance@usb.org to get a list of these Known Good Devices and Known Good Hubs. Any questions regarding KGDs or KGHs should be directed to ssusbcompliance@usb.org.

USB Type-C® IOP/CV Test Equipment
Please contact ssusbcompliance@usb.org for a list of devices used for USB PD and USB Type-C Interop Testing.  Please note the equipment list is expected to change periodically as equipment models are discontinued or reach end of life.

USB Certification Platform
Hosts, hubs and peripherals must be certified using Windows 11 (64-bit OS).  USB-IF testing must be done on:

DELL XPS8960 (11th Generation Intel® Core® i7 Processor, 8 GB Memory)

  • The latest Microsoft USB driver stack is used, and is updated by running Windows Update.  The BIOS should be updated to the latest version.  Please follow the PDK TechGuide document (TechGuide_xHCI_SSUSB_PDK_Ver2.5) for modifications to the DELL system being used.  If you have further questions about the system configuration, email usbcompliance@usb.org.

USB Compliance Devices

 

The following compliance devices are used in conjunction with compliance software to demonstrate USB hub or host compliance.  These devices are not designed for use with the windows stack, and are only to be used with host and hub specific tests.  Please address host or hub testing questions to usbcompliance.org.

Full Speed Compliance Device
Firmware requirements are handled through USB30CV software.  This is a bus-powered device.The Full Speed Compliance Device is available through the USB-IF here.

SuperMUTT
The Microsoft SuperMUTT operates as a Full Speed, High Speed, and SuperSpeed compliance device.  XHCICV and USB3CV can programmatically change the SuperMUTT to operate at the desired speed.  We recommend using the SuperMUTT instead of the older compliance devices.  Use SuperMUTT firmware version 57 or later.  The firmware updating utility can be downloaded here or directly from Microsoft.  Additional info can be found here: https://docs.microsoft.com/en-us/windows-hardware/drivers/usbcon/muttutil.   Ordering instructions are found here: https://docs.microsoft.com/en-us/windows-hardware/drivers/usbcon/microsoft-usb-test-tool--mutt--devices.  Contact usbcompliance@usb.org with any questions.

 

MCCI Compliance Device

This compliance device has a mode that allows it to operate like the Microsoft SuperMUTT.  It can operate at Full Speed, High Speed, USB 3.2 Gen 1x1 or USB 3.2 Gen 2x1 mode.  USB4CV requires use of this device for some USB3 tunneling tests.  The device can be ordered directly from MCCI at https://store.mcci.com/collections/usb-test-devices/products/model-3411.

Follow these directions to put the MCCI device into the correct mode for use with USB4CV and XHCICV: MCCI Mode Switch.

Best practice is to operate the MCCI device in self-powered mode.  It has been validated for XHCICV loopback tests and USB4CV Chapter 9 tests that need a USB3 loopback device, but not for XHCICV Interface Tests.
