You could probably add a feature to disable USB-3 functionality for a port.

On older systems the xhci controller only supports USB-3 and the USB-2 functionality
is provided by a separate ehci controller. Shouldn't be difficult to disable USB-3
there.

On newer systems the xhci controller learned to talk USB-2 as well. I'm not sure
if you can disable USB-3 there without disabling USB-2 at the same time.
