1 Using a USB device Universal Serial Bus (USB) is a hardware interface that can be used to connect an optional external device, such as a USB keyboard, mouse, drive, printer, scanner, or hub, to the computer or to an optional docking device. A hub provides additional USB ports for the system and can be connected to the computer or to another hub. This computer has one powered USB port and 2 standard USB ports that support USB 1.0, USB 1.1, and USB 2.0 devices. ■ The powered USB port (on the right side of the computer) provides power to external devices when used with a powered USB cable. ■ The other 2 USB ports do not provide power. External high-power devices connected to the USB ports that do not provide power must also be connected to AC power. Low power devices such as USB keyboards, mouse devices, and webcams do not require an AC power connection when connected to the 2 USB ports that do not provide power. An optional docking device provides additional USB ports that can be used with the computer. External Devices 1-1
