Well I’m in set up utility and for USB 3.0 configuration in pre-OS I have either in Enabled or Auto no disabled. It says when this option is set to enabled bios will configure USB ports to USB 3.0 controller. When the item is set to auto , bios Will configure USB ports to USB 2.0 controller in pre-boot . After booting to OS the USB ports will be switched to USB 3.0 controller. It is recommended to set to auto when installing OS which does not have native USB 3.0 driver such as windows 7 via USB optical device. I don’t see any other settings unless I’m in the wrong place .
