Data Fields

uint8_t AssociatedInputTerminal

uint16_t TerminalType

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_StdDescriptor_OutputTerminal_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

uint8_t USB_Audio_Descriptor_OutputTerminal_t::AssociatedInputTerminal

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

USB_Descriptor_Header_t USB_Audio_Descriptor_OutputTerminal_t::Header

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

uint8_t USB_Audio_Descriptor_OutputTerminal_t::SourceID

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

uint8_t USB_Audio_Descriptor_OutputTerminal_t::Subtype

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

uint8_t USB_Audio_Descriptor_OutputTerminal_t::TerminalID

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

uint8_t USB_Audio_Descriptor_OutputTerminal_t::TerminalStrIndex

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

uint16_t USB_Audio_Descriptor_OutputTerminal_t::TerminalType

Type of terminal, a TERMINAL_* mask.
