We recommend that you never connect audio interfaces to a USB hub, but always directly to the computer's port. Connect the USB cable between your computer and the interface.On Mac this is a Core Audio driver, on Windows there are various driver types available but ASIO is the best option. Windows users also have the option to install Asio4All which is a freeware universal audio driver.
A USB interface is used for this example. Most external audio interfaces use either USB, Thunderbolt or Firewire to connect to your computer. Audio interfaces generally improve the sound quality, allow you to achieve less latency and give you more options such as multiple inputs and outputs as well as record monitoring capabilities.
An audio interface allows you to connect microphones, instruments and other sources to your computer, so that you can record them into Live.
