Detailed Description

Type define for an Audio class-specific input terminal descriptor. This indicates to the host that the device contains an input audio source, either from 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_StdDescriptor_InputTerminal_t for the version of this type with standard element names.
Regardless of CPU architecture, these values should be stored as little endian.

Field Documentation

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

CHANNEL_* masks indicating what channel layout is supported by this terminal.

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

Regular descriptor header containing the descriptor's type and length.

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

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.

Total number of separate audio channels within this interface (right, left, etc.)
