There seems to originate a general misunderstanding from the other thread, where @Rulebreaker01 insisted yesterday that following your instructions all HS and SS ports assigned to internal USB3.0 headers should be denoted by 255. Doing that, sleep/wake broke immediately on my rig.
Thus.. thanks for confirming that my former approach, assigning 3 to the HS and SS ports of all internal USB3.0 headers connected to external devices was indeed always correct.
BTW.. I would not know any internal USB3.0 device connected to an internal USB3.0 header. Although apparently SS ports can be denoted by 255, I would rather say that 255 should be exclusively attributed to HS ports of internal USB2.0 headers, connected to internal USB2.0 devices. Opinion?
Both SSxx and HSxx can be connected to internal devices.
Although most internal devices tend to be USB2, there are existing examples of USB3 internal devices. One common case with desktops is an internal hub (may be part of the case or an internal hub on the board itself). And I've seen laptops with internal USB3 webcams.
In the future, we may see seeing USB3 BT controllers, trackpads, etc.
