Asus P4P800 SE - Manual (Page 52)

2-30 Chapter 2: Hardware information
7. USB headers (10-1 pin USB_56, USB_78)
If the USB ports on the rear panel are inadequate, two USB headers
are available for additional USB ports. The USB headers comply 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.
You must install the driver before you can use the USB 2.0 capability.
NEVER connect a 1394 cable to any of the USB (blue) connectors.
Doing so will damage the motherboard!
