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. Individual subranges must not overlap. If a subrange overlaps a previous one, it will be ignored by the driver. The USB Audio 2. The driver supports one single volume range only. If a feature unit implements single channel controls as well as a master control for Mute or Volume, then the driver uses the single channel controls and ignores the master control.
