Detailed Description

Type define for an Audio class-specific output terminal descriptor. This indicates to the host that the device contains an output audio sink, either to a physical terminal on the device, or a logical terminal (for example, a USB endpoint). See the USB Audio specification for more details.

See also:
USB_Audio_Descriptor_OutputTerminal_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

ID of associated input terminal, for physically grouped terminals such as the speaker and microphone of a phone handset.

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

Sub type value used to distinguish between audio class-specific descriptors, must be AUDIO_DSUBTYPE_CSInterface_OutputTerminal.

Size of the descriptor, in bytes.

ID value of the unit this terminal's audio is sourced from.

ID value of this terminal unit - must be a unique value within the device.

Index of a string descriptor describing this descriptor within the device.

Type of terminal, a TERMINAL_* mask.
