Bound to happen sooner or later, I disagree.
The two ports should be set as Internal.
They are connected to a USB2 motherboard header, which a Bluetooth module would also connect through. The Bluetooth moduel would have a connector type of 'Internal', so these two case ports should have the same connector type.
Bottom entry on the table below states the ports should be Internal (255).

The two case ports are connected to a Proprietary connector. The case cables connect them to a pair of Type-A ports, but that is not what they need to work, for sleep, instant reboots etc. Without being set to 255 they will not work correctly in macOS.
