I'm having an issue with my new build (GA-Z270X-UD5) and USB3. So I have the 200-series injector and the USBInjectAll kext along with the USB port limit patch but I'm not able to use USB3 devices on any of the USB3 ports (the single USB3.1 port on the back works with USB devices). I've been trying to read all the different posts on USB issues but I'm a little lost on what my next steps should be. When I look in IOReg under the XHC device, I only see HS ports listed there (HS01-HS14) along with a USR1. I believe I should be seeing a number of SS ports along with a USR2 under there as well. Could someone point me in the right direction? I've attached all the usual information for troubleshooting.
