Driver Installation
You may need to install the proper drivers in your system operation to use the USB device.
Refer to your operating system’s manual or documentation for more information.
Wake-On-USB Keyboard/Mouse
The Wake-On-USB Keyboard/Mouse function allows you to use a USB keyboard or USB mouse
to wake up a system from the S3 (STR - Suspend To RAM) state.
USB Ports
The USB device allows data exchange between your computer and a wide range of simultane-
ously accessible external Plug and Play peripherals.
The system board is equipped with 2 onboard USB 2.0 ports (USB 5-6), 2 onboard USB 3.1
Gen 1 ports (USB 1-2) and 4 onboard USB 3.1 Gen 2 ports (USB 3-4/5-6). The 10-pin connec-
tors allow you to connect 4 additional USB 2.0 ports (USB 7-8/9-10). The additional USB ports
may be mounted on a card-edge bracket. Install the card-edge bracket to an available slot at
the rear of the system chassis and then insert the USB port cables to a connector.
BIOS Setting
Configure these onboard USB devices in the Advanced menu (“USB Configuration” submenu)
of the BIOS. Refer to the chapter 3 for more information.
