Your Power Mac G4 comes with two USB ports (Figure 1) which you can use to connect many types of external devices, including printers, digital cameras, microphones, game pads, joysticks, keyboards, mouse devices, and storage devices. USB makes it easy to connect external equipment. Once you connect the device, it is ready to use. You don't need to restart your computer.

To use a USB device with your computer, connect the device to the computer and install its software or configure your computer to work with the device. From then on, your computer automatically loads the correct software whenever you attach the device.
Note: Apple has already included software to work with many USB devices. In most cases you do not need to install the software that came with the device. If, when you connect a USB device, your Power Mac G4 cannot find the correct software, it may ask you to search the Internet to find it.
Connecting Multiple USB Devices
Your keyboard or monitor may also have an available USB port that you can use to connect devices. If you want to connect more devices, purchase a USB hub. The USB hub connects to an open port on your computer and provides additional USB ports (usually four or seven). Search the Macintosh Products Guide for hub options.
