I installed USBinjectAll.kext and here's what mu ioreg looks like
View attachment Dave’s Mac Pro.ioreg
I see PR11-18 PR21-26 HP11-18 HP21-28...
most of the injectors I have seen mention HS and SSP do I need to install Yosemite just to get the proper ports?
I tried editing editing Matt's injector from post #1 and using it, but that got me nowhere, how do I start my own injector, I didn't see anything mentioning how to create the actual injector.kext file?
and how do I know what values to replace?
*edit: I just noticed HS01-14 and SSP1 on XHC... what that means, I'm not sure, researching further.
*edit again: if I use usbinjectall boot flag uia_exclude_xhc I see HSG4 and SSP1, 2, 4, 5, 6 only in XHC in ioreg.
Still have same result, one USB3 plug working on the front panel of my case and it shows up under XHC SSP2.
all the USB3 in the back connect to EH01 and work at USB2 speed.
