The USB ZED mixers are class compliant; they do not require drivers and use the built-in WDM drivers in Microsoft Windows and Apple's Core Audio drivers in Mac OSX.
Just plug the mixer into a computer via USB and you're ready to go, the device will present itself as 'USB Audio Codec' in your audio software or operating system.
Some DAWs, such as Reaper, may present the selection for USB Audio Codec under the audio system heading 'WaveOut'.
If you need to use an ASIO driver, we recommend the use of the free ASIO4ALL driver. After ASIO4ALL is installed, be sure to switch on the USB Audio Codec in the WDM Device List.
