However there is hardware where the system has this on the motherboard
but not wired to any jacks. Look for blue coloured ports or ones that
are labeled SuperSpeed (SS).  If those work then it is possible
(unless they have been wired into the USB-2 ports on the motherboard..
had to fix that on a system last month).

Finally if there is still doubt, check the BIOS of the system and if
it needs any updates. Various 'problems' with USB compatibility are
routinely 'fixed' by manufacturers after the system is shipped.
