USB XHCIWMI
XHCIWMI is a tool for diagnostic purposes. This tool only runs on Windows 8 and gathers information when the device is attached to an xHCI port and Windows loads the Microsoft USB 3.0 driver stack.
XHCIWMI
Run the following command in an elevated Command Prompt window:
Xhciwmi.exe
The tool shows the current firmware revision and information about the controller in the command window. Run the following command to verify the firmware of the controller and hub against known issues:
Xhciwmi.exe –verify
We recommend using the –verify option for checking the controller and the connected hubs.
