Hi there.What does one do in this situation? I'm working on 10.13.6 with the beyond security updates? Thank you.
In your case, not as hard as it seems.
Open IORegistryExplorer and with USBInjectAll installed but no Port-Limit Removal Patch, it will probably list the first 15 ports. HS01 to HS14 and USR01, or something similar. I would need to check your IOREG output to know for sure.
While your X79 chipset features the same 14-ports as a regular Intel Z-series does, it only has an EHC controller and not an XHC. The USB3 ports are instead controlled by a separate ASMedia chipset. These are not a part of the 15-port limit and not easily configurable. Hopefully they work okay. They probably appear on the PR or RP section of the IOReg tree.
Okay, so basically ignore the 4x back-panel USB3 ports and the 2x internal USB3 ports, do the plug-in test with a USB2 memory stick and map your regular USB2 ports. See what the total comes to. I reckon you have 14 in total - 6x back-panel and 8x internal.
If you are going to use an internal port for bluetooth then you need to map it so you can configure it as 'UsbConnector' value '255' etc. This can be done by using the case's front-panel port cable or by some other adapter etc.
With only 14x configurable ports you are under the limit anyway
