Universal Serial Bus (USB)
Your PowerBook comes with two USB ports, which you can use to connect many types of external devices, including printers, scanners, digital cameras, game pads, joysticks, keyboards, and hard disk drives. USB makes it easy to connect external equipment. In most cases you can connect and disconnect a USB device while the computer is running. Once you connect the device, it is ready to use. You don’t need to restart or reconfigure your computer.

Using USB Devices
To use a USB device with your computer, simply connect the device to the computer. Your computer automatically loads the correct software whenever you attach a new device.
Note: Apple has already included software to work with many USB devices. When you connect a USB device, if your PowerBook cannot find the correct software, 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.
USB Devices and Battery Power
USB devices, such as joysticks and keyboards, that get power from the USB connection instead of a separate power adapter can be used with your PowerBook. However, these types of USB devices can cause your PowerBook battery to become depleted faster. If you are going to have a device connected for an extended period, it is a good idea to plug in the power adapter.
