4. USB connectors (10-1 pin USB910; USB1112; USB1314)
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
480 Mbps connection speed.
Never connect a 1394 cable to the USB connectors. Doing so will damage the motherboard!
You can connect the front panel USB cable to the ASUS Q-Connector (USB, blue) first, and
then install the Q-Connector (USB) to the USB connector onboard if your chassis supports
front panel USB ports.
5. Optical drive audio connector (4-pin CD)
These connectors allow you to receive stereo audio input from sound sources such as
a CD-ROM, TV tuner, or MPEG card.
