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. Note: OS has to provide support for the xHCI controller in this
mode. If the OS does not provide support, all sharable ports won't work.
Disabled The USB 3.0 ports are routed to the EHCI controller and the xHCI controller is turned
off. All USB 3.0 devices function as High Speed devices regardless of xHCI software
support/availability.
