Please do not put a dummy control on your device. This goes against the
very philosophy of the audio system on Mac OS X.
I can't say this often enough or loud enough: You should present your
hardware as it is without faking anything.
If it doesn't have a volume control, please don't put a fake one there.
You'll save yourself the hassle of having to explain to your users why
it is there, but does nothing.
If you have a problem with how the System Prefs works, then you should
file a Radar bug. In this case, you don't have to because I filed it a
while ago. I can dig up the number if you are interested.

if they see a control and drag it around, but nothing happens.
Thanks,

Nope, that the way that code works. If there isn't a control then the
meter isn't drawn. I guess they feel it's not worth showing if you
can't do anything about it.
