34 Chapter 3 Using Your PowerBook
Using Universal Serial Bus (USB) Devices
Your PowerBook comes with two USB 2.0 ports (d), also referred to as Hi-Speed USB,
which you can use to connect many types of external devices, including printers,
scanners, digital cameras, game pads, joysticks, keyboards, and floppy disk drives. Your
USB 2.0 ports are compatible with earlier USB devices. In most cases, you can connect
and disconnect a USB device while the computer is running. After you connect the
device, it is ready to use. You don’t need to restart or reconfigure your computer.
To use a USB device with your computer, connect the device to the computer. Your
computer automatically detects newly connected devices and loads the correct
software to work with the device.
Note: If your PowerBook cannot find the correct software when you connect a USB
device, you can either install the software that came with the device or follow the
onscreen prompts to use the Internet to locate, download, and install the correct
software.
Understanding USB Devices and Battery Power
You can use USB devices, such as joysticks and keyboards, which are powered by the
PowerBook USB connection instead of a separate power adapter. However, these types
of USB devices can cause your PowerBook battery to become depleted faster. If you are
using the device for an extended period, it is a good idea to connect the PowerBook
power adapter.
