Reference software

USB Audio 2.0

Our USB Audio 2.0 reference software offers different control functionality, such as device firmware update (DFU) and human interface device (HID). It’s provided as source code and is available to all registered USB audio customers.

If you're a licensee of Apple’s MFi programme, we also provide hardware and software solutions that enable Apple devices to operate in USB Host Mode and in USB Device Mode with support for USB Role Switch. We’ll need to check your MFi registered number before releasing this software to you.

We provide a free Windows USB audio driver for evaluation and prototyping, a free stereo-only driver for production and a part for a more feature-rich multichannel production driver. We do not provide drivers for third party USB products, even if they use XMOS chipsets internally - please contact your supplier for help.
