6. 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.
7. 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.
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.
