How to Use a USB Hub on a MacBook (3 Steps)

Plug the power adapter of the USB hub into the wall outlet, if you are using a self-powered USB hub. Self-powered USB hubs provide more power to any connected devices than bus-powered USB hubs.
Insert the USB connector of the hub into the USB port closest to you when you face your MacBook.
Plug your USB devices into the ports on the hub. Some devices run solely on the power from the USB connection, while others include a plug for a wall outlet. Your devices will be active as soon as they are connected and have power.
