Installing an extra USB card in one of the computer's PCI/PCIe slots will also do the trick, as USB3CV hijacks a specific controller, not all of them. Or some low-level Windows trickery to manually change the assigned driver for a given PCI/PCIe device (i.e. the hijacked USB controller). Device manager, maybe?

I can start the machine in recovery mode but unfortunately there isn't a recovery point. Ther's a way for remove the USB3CV and restore the original USB Host controller?
