For instance, an iMic is recognized (as actually 2 software devices)

If I create a FireWire device that has n-inputs and n-outputs, how do I
let core-audio know that the inputs and outputs exist as core-audio
device(s)?
Because the driver that loads for the camera is not a driver that is a
child of the IOAudioFamily, but more a global Audio/Video firewire
driver. The matching process does depend on the info in the firmware of
the device.
If there was a generic AppleFWAudio driver that was an IOAudio Family
driver, and if the matching information for it (as wellas the probe
function of the driver) was returning a higher score than the
Audio/Video driver then it would load....as an audio device only.
