The Audio Advantage Amigo does not require special drivers or software. Just insert it into any USB port on your Mac or Windows PC or laptop and the operating system will recognize and install the Amigo. If you are using a really old version of Windows and the device doesn't appear for whatever reason you could try the drivers from the Audio Advantage Micro as it probably is the similar or the same device.
