USB 3.0 Mode

Use this option to set the mode in which USB 3.0-capable devices operate.

• Auto—USB 3.0-capable devices operate at USB 2.0 speeds in the pre-boot environment and during boot. When a USB 3.0 capable OS USB driver loads, USB 3.0 devices transition to USB 3.0 speeds. This mode is compatible with operating systems that do not support USB 3.0 while still allowing USB 3.0 devices to operate at USB 3.0 speeds with modern operating systems.
• Enabled—USB 3.0-capable devices operate at USB 3.0 speeds at all times (including the pre-boot environment) when in UEFI Boot Mode. Do not use this mode with operating systems that do not support USB 3.0. When operating in Legacy BIOS Boot Mode, the USB 3.0 ports do not function in the pre-boot environment and are not bootable.
• Disabled—USB 3.0-capable devices function at USB 2.0 speeds at all times.
