When set to Disabled, BIOS disables USB 3.0 mode for all the USB3.0 ports. The USB devices operate at USB2.0 mode. When set to Enabled, BIOS operates all USB3.0 ports at USB2.0 mode during POST, and switches them to USB3.0 mode right after the operating system (OS) boots. You must select this option only if the operating system (such as. Windows Server 2012) has a native USB 3.0 driver. Otherwise none of the USB devices will work after boot. The Auto option is available only on workstation servers. If this option is selected, the BIOS leaves all USB 3.0 ports at USB 2.0 mode, and a special OS switching driver is required to set the USB3.0 port to USB3.0 mode. Microsoft Windows 7 has switching driver capability.
