USB 3 Command Verifier (USB3CV) is the official tool for USB 3 Hub and Device Framework testing. All USB 3.1 peripherals are required to pass the Device Framework tests in order to gain certification. The USB3CV tool includes the xHCI Compliance Drivers for use with the USB3CV. In order to use USB3CV, User Account Control (UAC) must be turned off. If you are running on 64-bit Windows, you must install the 64-bit CV.
