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.
uint16_t USB_Audio_StdDescriptor_Interface_AC_t::bcdADC |
Binary coded decimal value, indicating the supported Audio Class specification version.
uint8_t USB_Audio_StdDescriptor_Interface_AC_t::bDescriptorSubtype |
Sub type value used to distinguish between audio class-specific descriptors, a value from the Audio_CSInterface_AS_SubTypes_t enum.
uint8_t USB_Audio_StdDescriptor_Interface_AC_t::bDescriptorType |
Type of the descriptor, either a value in USB_DescriptorTypes_t or a value given by the specific class.
uint8_t USB_Audio_StdDescriptor_Interface_AC_t::bInCollection |
Total number of Audio Streaming interfaces linked to this Audio Control interface (must be 1).
uint8_t USB_Audio_StdDescriptor_Interface_AC_t::bInterfaceNumbers |
Interface number of the associated Audio Streaming interface.
uint8_t USB_Audio_StdDescriptor_Interface_AC_t::bLength |
Size of the descriptor, in bytes.
uint16_t USB_Audio_StdDescriptor_Interface_AC_t::wTotalLength |
Total length of the Audio class-specific descriptors, including this descriptor.
