cool_recep Posted April 18, 2017 Share Posted April 18, 2017 Hi I am trying to install Sierra on Rampage IV Gene but I can't get the USB 2.0 ports to work. BIOS: EHCI Hand Off Enabled USB 2.0 Legacy Support Enabled USB 3.0 Legacy Support Enabled Virtualization: Disabled Clover: Tried all settings including: USB Inject USB ClockID USB Ownership I have was able to use my USB 3.0 ports with GenericUSBXHCI.Kext but no luck with 2.0. BIOS version: 4901. Do I need an SSDT? Thanks. Link to comment Share on other sites More sharing options...
