Note: This is the recommended mode when BIOS has xHCI preboot support. (Default) 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. Enabled All shared ports are eventually routed to the xHCI controller during the BIOS boot process.  If BIOS does not have pre-boot support for the xHCI controller, it should initially route the sharable ports to the EHCI controller and then prior to OS boot it should route the ports to xHCI controller. If the OS does not provide support, all sharable ports won't work. Disabled  USB 3. 0 ports are routed to the EHCI controller and the xHCI controller is turned  The off. All USB 3. 0 devices function as High Speed devices regardless of xHCI software support/availability. Manual Allows you to determine whether to rout the USB 3. 0 ports to the xHCI or EHCI controller  before booting to OS, and also provides you with options to manually rout each USB 3. 0/2. 0 port to xHCI or EHCI.
