Hi All,

Just got my new i7 7700K, GA-Z270X-Ultra Gaming, GTX 1070 with Sierra running, boots fine, and nvidia driver seems fine too. But I've been struggling for hours now reading up on how to Fix USB 3.0, still no dice, the System Information shows that plugged in USB devices are only up to USB 2.0 speed. I've already installed USBInjectAll.kext, FakePCIID_XHCIMux.kext, Generic USBXHCI.kext and XHCI-200-series-injector.kext. I have them in EFI/ClOVER/kext/ in both 10.12 folder and other, and also in S/L/E/ and L/E . I'm not sure which folder I should really have them installed in. I also used Kext Beast to install them to S/L/E/ and L/E/. Any advice would be greatly appreciated. Thanks.

Update: after patching
APCI>DSDT>Patches>
add change EHC1 to EH01
add change EHC2 to EH02
It seemed to work. Not 100% sure if that was what caused the kext to work, but it works now!
