USB Audio Driver Support

The XMOS USB Audio firmware supports both USB Audio Class 1.0 and USB Audio Class 2.0.
Operation with a USB Audio Class 2.0 host is preferred because of its extended feature set and use of USB 2.0.

Apple OSX version 10.6.4 and above natively supports USB Audio Class 2.0 – no driver install is required.
Windows, however, only provides support for USB Audio Class 1.0. To use a USB Audio Class 2.0 device under Windows requires a driver. XMOS therefore provides a free Windows USB Audio driver for evaluation and prototyping, a free stereo-only driver for production, and a path to a more feature-rich multichannel production driver from Thesycon.

Evaluation and production Windows drivers are also available from our partners CEntrance or Ploytec.

NOTE: XMOS does not provide drivers for third party USB products, even if they use XMOS USB chipsets internally. If you need a driver for your USB device, please contact your supplier who will be able to provide you with a drivers for their product.
