XHCI (USB3) not showing in PCI list

Recommended Posts

Hi !!

I have a Dell Optiplex 7010 (Q77, 7-series) running an i7-3770 with the standard Intell 4000 HD. I want to enable USB3 but all ports show as USB2. Listing the OCI devices shows THERE IS NO XHCI controller. Any suggestions??

Which kext did you use?

USBinjectall.kext can make USB3.0 work.

Or, in my case, I load appleUSBXHCI.kext to get my usb3.0 work.

For the worst case, you have to patch DSDT for the full use of USB.
