7. USB headers (10-1 pin USB11_23, USB20_12)
If the USB port connectors on the rear panel are inadequate, two USB
headers are available for additional USB port connectors. The header
labeled USB11_23 complies with the Universal Serial Bus (USB) 1.1
specification. Connect the bundled 2-port USB connector set to this
header and mount the USB bracket to an open slot in the chassis.
The other USB header (blue) complies with USB 2.0 specification that
supports up to 480 Mbps connection speed. This speed advantage
over the conventional 12 Mbps on USB 1.1 allows faster Internet
connection, interactive gaming, and simultaneous running of high-
speed peripherals.
If your package came with a GAME/USB 2.0 module, connect the USB
cable to this header. The module has two USB 2.0 ports that support
the next generation USB peripherals such as high resolution cameras,
scanners, and printers.
