USB connectors (10-1 pin USB78, USB910, USB1112)

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 specification that supports up to 

480Mbps connection speed.

Never connect a 1394 cable to the USB connectors. Doing so will damage the 

motherboard!

The USB 2.0 module is purchased separately.

This connector allows you to receive stereo audio input from sound sources such as a 

CD-ROM, TV tuner, or MPEG card.
