Note: Apple has included software to work with many USB devices. When you connect a USB device, if your iMac cannot find the correct software, install the software that came with the device or check the manufacturerÕs website for the latest software.

Using Multiple USB Devices at the Same Time

If all of your USB ports are being used and you want to connect more USB devices, you can purchase a USB hub. The USB hub connects to an open USB (d) port on your iMac and provides additional USB ports (usually four or seven). Most USB hubs also have a power adapter that should be plugged into an outlet.
