USB (Universal Serial Bus) Connector
(USB1, USB2)
USB is an open industry standard, providing a simple and inexpensive way to
connect up to 125 devices to a single computer port. Keyboards, Mouse tablets,
digitizers, scanners, bar-code readers, modems, printers and many more can all
run at the same time. USB is a dynamically reconfigurable serial bus with an
elementary data rate of 12Mbps, based on off the shelf, low cost micro-controller
technology. Its modular layered software protocol supports sophisticated devices
and application programs. This board contains a USB Host controller and
includes the root hub with two USB ports (meet USB Rev 1.0 spec.), which
permits the connection of two USB peripherals or hub devices directly.

If a PS/2 Mouse is used, you should enable PS/2 function
from BIOS, then BIOS will assign IRQ12 to PS/2 Mouse.
