USB 2.0 Command Verifier

http://www.usb.org/developers/tools/

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 are required to pass the Device Framework tests in order to gain certification. The other tests are mandatory for certification when supported. If you have installed a previous version of the USB 2.0 Command Verifier, you must uninstall it before installing the new version

  • USBCVは走っている間はWindowsのUSBスタックを置き換え、完全にUSBを乗っ取ります。USBマウス、キーボードは通常の使用はできません（テスト対象となってしまう）。ノートＰＣのキーボード、パッドなどは通常内部でPS/2で接続されているのでＯＫです。

Release Notes
April 2, 2015
USB Command Verifier
·	You must uninstall any previous versions of USB20CV before installing.  The USB20CV installer does not uninstall earlier versions of USB20CV.  You must do it yourself.
·	USB 2.0 Command Verifier (USB20CV) is a new tool that replaces the old USBCheck. This tool has been tested on Windows 7, Windows 8 and Windows 8.1 with the latest service packs and updates installed in each case.
·	For Windows 7, Windows 8 and Windows 8.1, User Account Control (UAC) must be turned off. After turning off UAC, the system must be rebooted in order for the changes to take effect.
　·	Windows 7, Windows 8 and Windows 8.1 must be run with Driver Signature Enforcement disabled. 
　·	For Windows 7:  At system start-up, press F-8 for Advanced Boot Options screen, then select Disable Driver Signature Enforcement.
　·	For Windows 8 and Windows 8.1:  
　　·	Go to the Settings screen by moving the mouse to the bottom right corner of the screen and then moving it up to select the Settings icon.
　　·	Holding the shift key down, click on the Power icon and select Restart.  In a few seconds, this will take you to the Choose An Option screen.
　　·	Select Troubleshoot
　　·	Select Advanced Options
　　·	Select Startup Settings
　　·	Select Restart.  This will reboot the computer.  When Windows 8 starts up again, you will be taken to a Startup Settings screen.
　　·	Select Disable driver signature enforcement.
·	This tool requires that Microsoft XML (MSXML) version 6.0 be installed on your computer.  This is the default version for Windows 7 and Windows 8.  If necessary, it can be downloaded from www.microsoft.com.
·	You will need a browser to view the results of the test.
·	This version of the tool requires that you have at least one EHCI compliant USB 2.0 host controller card in your system. Further, to test full and low speed hubs/devices a USB2.0 HUB is required.
·	A description of the tests that USB20CV performs is provided in the USB Command Verifier Compliance Test Specification.
·	This version of the tool supports the use of mouse and keyboard plugged directly into the root ports of the USB 2.0 host controller on your system.

To complete the installation:
Download the Company list file (USB.if)
·	You can get this file at http://www.usb.org/developers/tools.  Follow the instructions to download the company list and save the file under the lib subdirectory where USB20CV was installed. (default path C:\Program Files\USB-IF Test Suite\USBCommandVerifier\lib).

Using USB20CV:
Usage Models/Restrictions
·	This version of the tool requires that you install the eHCI compliance driver for your eHCI-based host controller prior to running USB20CV.
·	A device to be tested must be connected to the system, either directly or to a USB 2.0 Hub (in the case of a full/low speed device) in order for the test suite to detect it and perform tests on it.
·	Devices connected down stream of a hub under test (only applies to Hub tests) must be capable of remote wakeup. Preferably use mice.
·	Upon completion of a test an html report is created in the Reports subdirectory where USB20CV was installed.

 
Testing High Speed Capable Devices
·	In order to test high speed mode of high speed capable devices, the device can be connected directly to the root port of the EHCI compliant USB2.0 controller or to an A-receptacle of a USB 2.0 hub.
·	In order to test full speed mode of high speed capable devices, the device must be connected below a full speed (USB 1.1) hub. The full speed hub must then be connected to the EHCI based host controller behind another high speed hub.

Testing Full/Low Speed Capable Devices
·	Full or Low speed devices must be connected behind a high speed USB 2.0 hub in order to be tested.

USB20CV Warnings
At the present time, there is no plan to change any warnings to failures.

Uninstalling USB Command Verifier
·	Use the Add/Remove Programs control panel applet to remove USB20CV.

Known Issues
·     CV crashes intermittently during or after running the Report Descriptor Test in the HID test suite.
Work-around: There is no reliable work-around at this time.  The following actions have sometimes been effective:
detaching and reattaching Device Under Test..  
re-running the tests: if CV crashes after the test completes, there may be output files (either HTML or a BAK) with full test results.

Bug reports
·	Send all bug reports to TechAdmin@usb.org <mailto:TechAdmin@usb.org>.
