USBCVV1.3.2

The installation utility, InstallUSBCV132.msi (4MB) contains USB Command Verifier (USBCV) version R1.3.2 and documentation. USBCV R1.3.2 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 are required to pass the Device Framework tests in order to gain certification.  The other tests are mandatory for certification when supported.

USBCV revision 1.3.2 is the official test tool for device framework testing.  As of April 2007, the mass storage class tests and the video class tests are official and mandatory.  This software is provided courtesy of Intel Corporation.      

NOTE: Please do not install this tool on a machine that already has previous versions of USBCV installed.   This software release will work on Windows XP SP2 (English version only) with all critical patches installed or on Windows Vista with User Access Control disabled.  This tool requires an Enhanced Host Controller Interface, EHCI.  If testing Full or Low-speed devices, an intervening Hi-Speed USB Hub is required.  USBCV R1.3.2 uses a special purpose driver for the Hi-Speed USB Host Controller.  USBCV R1.3.2 automatically replaces the standard Microsoft EHCI host driver with its own test stack driver.  When USBCV R1.3.2 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.
