Disabled – USB ports will function in USB2.0 mode only. No USB3.0 OS driver required. The USB ports will be
routed to EHCI1 controller.
Enabled – USB ports will function correctly in BIOS but the ports on which the USB3.0 mode is enabled (see USB0

function in pre-OS time if USB3.0 Support in BIOS is disabled (see the USB3.0 Support in BIOS item).
Auto – USB ports are initially set to operate in USB2.0 Mode and the USB3.0 OS driver (if available) will switch
them USB3.0 mode. If USB3.0 OS driver is not available than the ports will function correctly but they will operate in
USB2.0 mode.
Smart Auto – The BIOS will store the USB mode set by the OS and at next boot the BIOS will set this previously
used mode. At G3 boot (first boot after mechanical disconnection of the power supply) the USB ports will function
identically as in Auto mode. This mode is not available when Disabled is selected at USB3.0 Support in BIOS item.
