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.

EHCI-based Test Tools

USB20CV

USB20CV is the compliance test tool which evaluates High, Full and Low-speed USB devices for conformance to the USB Device Framework (Chapter 9), Hub device class (Chapter 11), HID class, and OTG specifications. Also included are mass storage class and USB video class specification tests.  All USB peripherals and hubs are required to pass the Device Framework tests in order to gain certification. The other tests are mandatory for certification when supported. This tool takes control over the USB host controller and renders all products connected to it unusable. USB2CV should not be installed an oscilloscope or any system that uses USB as its only form of input from the user.

The USB20CV tool Ver. 1.5.15.0 is available below

NOTES

  • If you have installed a previous version of the USB 2.0 Command Verifier, you must uninstall it before installing the new version
  • The USB20CV tool is supported on Windows 7 and above only.
  • Please download the Company List and save as usb.if in the same directory as USB20CV.
  • Please do not install this tool on a machine that already has previous versions of USB20CV installed. This tool requires an Enhanced Host Controller Interface, EHCI. If testing Full or Low-speed devices, an intervening Hi-Speed USB Hub is required. USB20CV uses a special purpose driver for the Hi-Speed USB Host Controller.  USB20CV automatically replaces the standard Microsoft EHCI host driver with its own test stack driver. When USB20CV exits, the original standard Microsoft EHCI host driver is restored. Stack switching has been extensively tested with Microsoft EHCI drivers only. Stack switching has not been tested with USB 2.0 host controller drivers provided by other vendors. Please read the Release Notes for details

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.
