Mojave registry not seeing USB 3 ports at all

I've been doing lots of homework in this subreddit, as well as on Tonymacx86 and Googling in general, regarding the USB port limit removal tools and creating a custom SSDT in order to have USB 3.0 ports behave correctly in Mojave 10.14.4, but one thing that keeps coming up is confounding me.

Using IORegistryExplorer, one should supposedly be able to at least see the virtual USB 3.0/3.1 ports that correspond to the physical ports on a motherboard, labeled as SSxx, as opposed to HSxx for USB 2.0 virtual ports. But as you can see from my attached image, IORegistryExplorer isn't even doing that. Where I have gone wrong? I have tested all my ports with a 2.0 flash drive, as well as a 3.0 external hard drive. Only the flash drive (and other non-storage peripherals, like the mouse and wireless keyboard already displayed in IORE) work. What else do you need to know from me, miracle workers?
