The following USB specifications define USB Audio and are referenced in this article. The usbaudio2.sys driver fits within the wider architecture of Windows USB Audio as shown. However, if a third-party driver exists on the system or Windows Update, that driver will be installed and override the class driver. The driver is automatically enabled when a compatible device is attached to the system. This name will be overwritten with a USB product string, if it's available. The driver will identify in device manager as 'USB Audio Class 2 Device'.
The driver is named: usbaudio2.sys and the associated inf file is usbaudio2.inf. The driver is a WaveRT audio port class miniport. It's designed to support the USB Audio 2.0 device class.
Starting with Windows 10, release 1703, a USB Audio 2.0 driver is shipped with Windows.
