Detailed Description

Type define for an Audio class-specific interface descriptor. This follows a regular interface descriptor to supply extra information about the audio device's layout to the host. See the USB Audio specification for more details.

See also:
USB_Audio_Descriptor_Interface_AC_t for the version of this type with non-standard LUFA specific element names.
Regardless of CPU architecture, these values should be stored as little endian.

Field Documentation

Binary coded decimal value, indicating the supported Audio Class specification version.

Sub type value used to distinguish between audio class-specific descriptors, a value from the Audio_CSInterface_AS_SubTypes_t enum.

Type of the descriptor, either a value in USB_DescriptorTypes_t or a value given by the specific class.

Total number of Audio Streaming interfaces linked to this Audio Control interface (must be 1).

Interface number of the associated Audio Streaming interface.

Size of the descriptor, in bytes.

Total length of the Audio class-specific descriptors, including this descriptor.
