THis thread is about Series 8 and 9 so when i say on newer macs i mean haswell macs, I did not make this guide for laptops or old hacks at all. I have said this many many times so please stop correcting me. Those who want to use your methods are free to do so. All my haswell/Broadwell Macs have no XHCI at all in the DSDT, SSDT or otherwise so this is how I chose to do mine. If you don't like this stick to your own methods please.
Apple has changed the way the new USB stack works and only uses XHCI now.The USB stack in 10.11 is new for both XHCI and EHCI. You did not specify you were referring only to the USB stack running on certain Macs.
Your comment regarding FakePCIID_XHCIMux.kext is wrong, and I provided correct information regarding it.
