Subject: USB iMic

The Griffin iMic looks like a promising audio gadget:
http://www.griffintechnology.com/audio/imic_main.html
Plugging it in, the following device nodes are reported by the kernel:
14,19 # /dev/dsp1
14,16 # /dev/mixer1
14,32 # /dev/mixer2
The Linux mixer programs like "aumix" and "xmixer" see the "Mic"
input on the mixer1 device, but there are no slider controls for
controlling gain.
Anyone have suggestions how to get it to work?
Thanks,
