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. 1.5.13.0 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
