Some common USB devices are analog only, so prevent the digital
devices from being opened. This simplifies probing the device
in PulseAudio.
I have a "Logitech USB Headset" myself, the "Logitech Web Camera"
was reported by Raymond Yau, and the "Blue Snowball" was reported by
Andy Whitcroft.

How do the blacklist work ? since there is no "Logitect Web Camera" in
lsusb info
My QuickCam Communicate Deluxe only support mono, so it is unlikely
for pulseaudio to open for digital capture

Sorry, maybe I misunderstood you then - could you give me the contents
of "/proc/asound/cards" please?
