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?
It only support 16000Hz mono and S16_LE analog capture
