USB 3.1 missing GA-Z270x-UD3 under Sierra

[danielgrapes]

I have successfully installed the latest Sierra on my first hackintosh, got the nVidia gtx card working with the webdrivers after a couple of tries
The only issue I have left is that in the sys report I only see USB 3.0 and USB 3.1 is missing.

I installed the generic usb driver and the raise port limit extension.

I was searching extensively on the forum to find the corresponding topic, but I could not find the right one yet.

Is this issue can be solved by writing my on SSDT, or is there a more easier solution?

I appreciate all your input, thank you

O.K. it turned out that /Library/Extensions/GenericUSBXHCI.kext was the issue.
I removed that and the card seems to be working fine.

This worked perfect for my usb 3.1 on asus maximus ix z270. so simple
