It is designed to support the USB Audio 2. The driver is a WaveRT audio port class miniport. For more information about the USB Audio 2. The driver is named: usbaudio2. This name will be overwritten with a USB Product string, if it is available. The driver is automatically enabled when a compatible device is attached to the system.
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 supports the formats listed below. An alternate setting which specifies another format defined in FMT-2, or an unknown format, will be ignored.
The driver supports one single clock source only. For the asynchronous OUT case the driver supports explicit feedback only. A feedback endpoint must be implemented in the respective alternate setting of the AS interface. The driver does not support implicit feedback.
For the Adaptive IN case the driver does not support a feedforward endpoint. If such an endpoint is present in the alternate setting, it will be ignored.
The size of isochronous packets created by the device must be within the limits specified in FMT A function with an audio control interface but no streaming interface is not supported. The driver supports all descriptor types defined in ADC-2, section 4.
The following subsections provide comments on some specific descriptor types. An AS interface descriptor must start with alternate setting zero with no endpoint no bandwidth consumption and further alternate settings must be specified in ascending order in compatible USB Audio 2. Each non-zero alternate setting must specify an isochronous data endpoint, and optionally a feedback endpoint. A non-zero alternate setting without any endpoint is not supported.
The bTerminalLink field must refer to a Terminal Entity in the topology and its value must be identical in all alternate settings of an AS interface. For Type I formats, exactly one bit must be set to one in the bmFormats field of the AS interface descriptor. Otherwise, the format will be ignored by the driver. To save bus bandwidth, one AS interface can implement multiple alternate settings with the same format in terms of bNrChannels and AS Format Type Descriptor but different wMaxPacketSize values in the isochronous data endpoint descriptor.
For a given sample rate, the driver selects the alternate setting with the smallest wMaxPacketSize that can fulfill the data rate requirements. The driver supports a subset of the control requests defined in ADC-2, section 5. The following table shows the subset that is implemented in the driver. Each subrange describes a discrete frequency, or a frequency range. Download driver Windows 11, 10, 8.
