Hello there.Attached is the file detected by IORegistryExplorer. Can someone help me identify the abbreviations to watch?
It depends on why you are asking?
Because this is a USB thread, it looks as though:
1) you have both the EHCI and XHCI controllers active.
2) your motherboard has just 4x USB3.0 ports and 6x USB2.0 ports controlled by your Z97 chipset. This equates to 14-ports (4x2 + 6) that need configuring and below the 15-port limit.
3) No need for FakePCIID_XHCIMux.kext.
4) Your 'piggy-back' Renesas 3rd-party USB 3.0 ports do not form a part of the 15-limit and do not always need to be configured. A few years ago a kext was produced that did this, called GenericUSBXHCI.kext. However it might not work with macOS Catalina. There were problems with Mojave and High sierra too. The kext was written in 2015.
