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.
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.
