USB 2.0 connectors (10-1 pin USB78, USB910)
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.
