I think the dBmin and dBmax values provided in the mixer description are incorrect, both are 0.

$ cat /proc/asound/CameraB409241/usbmixer
USB Mixer: usb_id=0x14152000, ctrlif=1, ctlerr=0
Card: OmniVision Technologies, Inc. USB Camera-B4.09.24.1 at usb-0000:00:1a.7-5.2, hi
  Unit: 3
    Control: name="Mic Capture Volume", index=0
    Info: id=3, control=2, cmask=0xf, channels=4, type="S16"
    Volume: min=0, max=1, dBmin=0, dBmax=0

Also note 'Mic Gain' control in my previous post is the result of my .asoundrc configuration, not an actual Playstation Eye control.
