uint16_t index ()

the 16 bit index which needs to be used any time a command needs to be

sent to this unit (the wIndex field). This is formed from the unit ID

(high byte) and the control interface id (low byte).

zx_status_t Probe (const usb_protocol_t & proto)

A hook which allows certain audio units/terminals to read their

capabilities at startup. Not all of the units need to do this, so the

default hook implementation is a no-op.

uint32_t source_count ()

Every audio unit needs to define which source(s) feed it. This

information is contained in the unit/terminal's descriptors, but where it

lives (and whether or not it is simply implied, such as in the case of an

InputTerminal) depends entirely on the type of unit/terminal in question.

Because of this, we simply model the interface using pure virtual

methods.

uint32_t source_id (uint32_t ndx)

bool & visited ()

A state flag used by the audio control interface class when it is

searching the terminal/unit graph for audio paths to publish.

Defined at line 73 of file ../../src/media/audio/drivers/usb-audio/usb-audio-units.h

bool in_use ()

A flag indicating whether or not there is at least one audio path in the

system attempting to use this unit/terminal
