Connecting Multiple USB Devices

Your computer has two USB ports built in. If you are using an Apple Studio Display or Apple Cinema Display with your computer, you have two additional USB ports to which you can connect your keyboard and speakers.

Important Do not attach your speakers to the USB ports on your keyboard or to an external USB hub. They are not designed to support your speakers. Plug your speakers into a USB port on your computer, or into the USB ports on an Apple Studio Display or Apple Cinema Display that has an ADC cable.

If you have more USB devices than you have available USB ports, purchase a USB hub. The USB hub connects to an open port on your computer and provides additional USB ports (usually four or seven).
