Ok, before this gets hopelessly unproductive, please describe what
you are aiming at and operating on in greater detail.

It looks to me like you have an audio device that is connected
to the host by USB _and_ another bus. Is that correct?
Will you submit the "subdriver" that drives the device over
that secondary bus?
The operation over the secondary bus requires a hook in USB
power management. Why?

Secondly, the naming is atrocious.

Now could we please first define the technical nature of the issue,
so that we fully understand it before we debate the desirability?
