Connecting USB devices Universal Serial Bus (USB) is a serial bus design that is capable of
cascading peripherals such as a digital camera, keyboard, mouse,
joystick, scanner, printer and modem. With USB, complex cable
connections can be eliminated.
Your computer comes with eight USB ports: four on the front and
another four on the rear panel. These ports support USB 2.0 high-
performance external devices such as webcams and digital still
cameras. They also allow you to connect additional USB devices to your
computer without using up its system resources.
To connect a USB device, simply plug the device cable into any of the
USB ports (black port).
Note: Some USB devices have a built-in USB port which allows you
to connect or daisy-chain more USB devices.
