Enter OS, the USB port disabled in prior step is still functional (expected: USB port disabled).
Why my all USB ports are not working?
Right-click the first USB controller under Universal Serial Bus controllers, and then click Uninstall to remove it. ... After the computer starts, Windows will automatically scan for hardware changes and reinstall all the USB controllers that you uninstalled. Check the USB device to see whether it is working.
