This connector is for additional USB 3.0 ports. Connect the USB 3.0 bracket cable to
this connector, then install the USB 3.0 bracket to the rear side of the chassis. If your
chassis supports front panel ports, you can use the ASUS USB 3.0 header to install
additional front panel USB 3.0 ports.
The USB 3.0 module is purchased separately.
9. USB 2.0 connectors (10-1 pin USB56, USB78)
These connectors are for USB 2.0 ports. Connect the USB module cable to any of
these connectors, then install the module to a slot opening at the back of the system
chassis. These USB connectors comply with USB 2.0 specifications and supports up to
480Mbps connection speed.
Never connect a 1394 cable to the USB connectors. Doing so will damage the
motherboard!
