XHCI Mode
Allows you to determine the operating mode for the xHCI controller in OS.
Smart Auto : This mode is available only when the BIOS supports the xHCI controller in the pre-boot environment.
This mode is similar to Auto, but it adds the capability to route the ports to xHCI or EHCI according
to setting used in previous boots (for non-G3 boot) in the pre-boot environment. This allows the use
of USB 3.0 devices prior to OS boot. xHCI controller enabling and rerouting should follow the steps
in Auto, when previous boot routs ports to EHCI. Note: This is the recommended mode when BIOS
has xHCI preboot support.
Auto : BIOS routes the sharable ports to EHCI controller. Then it uses ACPI protocols to provide an option to
enable the xHCI controller and reroute the sharable ports. Note: This is the recommended mode
when BIOS does NOT have xHCI pre-boot support. (Default)
