4. USB connectors (10-1 pin USB78, USB910, USB34, USB56)
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.
The USB module cable is purchased separately.
5. USB 3.0 front panel connector (19-pin USB3_56)
This connector supports several two additional USB 3.0 ports.
