Besides four default USB 2.0
ports on the I/O panel, there are
three USB 2.0 headers on this
motherboard. Each USB 2.0
header can support two USB
2.0 ports.

port cable that allows
convenient connection of printer
devices.
This header supports an
optional wireless transmitting
and receiving infrared module.
This connector allows you
to receive stereo audio input
from sound sources such as
a CD-ROM, DVD-ROM, TV
tuner card, or MPEG card.
