USB Ports
The USB device allows data exchange between your computer and a wide range of simultane-
ously accessible external Plug and Play peripherals.
In addition to the rear USB ports as introduced previously in this chapter, the system board is
equipped with an internal USB 3.0 and USB 2.0 ports as illustrated above.
The internal USB pin headers may be connected to 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 the onboard USB in the Advanced menu (“USB Configuration” submenu) of the
BIOS. Refer to chapter 3 for more information.
Wake-On-USB Keyboard/Mouse
