1.8.14 USB 2.0 Connector (USB56)
These connectors are for USB 2.0 ports. Connect the USB/GAME 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 480
Mbps connection speed.
Never connect a 1394 cable to the USB connectors. Doing so will
damage the motherboard!
The USB module is purchased separately.
