10. USB headers (10-1 pin USB_56, USB_78)
If the USB ports on the rear panel are inadequate, a USB header is
available for additional USB ports. The USB header complies with USB
2.0 specification that supports up to 480 Mbps connection speed. This
speed advantage over the conventional 12 Mbps on USB 1.1 allows
faster Internet connection, interactive gaming, and simultaneous
running of high-speed peripherals.

NEVER connect a 1394 cable to the USB_56 or USB_78 connectors.
Doing so will damage the motherboard!

package.
