Godfrey,
My driver isn't loading.
I backed up to two apple supplied sample programs:
<http://developer.apple.com/samplecode/SampleUSBAudioPlugin/SampleUSBAudioPlugin.html>
and
<http://developer.apple.com/samplecode/SimpleUserClient/SimpleUserClient.html>
SimpleUserClient is showing up in the io registry.
SampleUSBAudioPlugin isn't.
How force SampleUSBAudioPlugin to load?
TIA,
Wayne
