The Audio Advantage Amigo II 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 II. 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 II as it probably is the similar or the same device.
