Interesting.
As it turns out the USB headset/microphone that I bought was missing its USB interface module. The manufacturer has very graciously sent me a new one, but the tech support guy made some very discouraging noises about the possibility of using it with Linux (for the record, it's a Telex, and their other microphones actually work quite well with the USB audio driver).
Guess I'll be getting acquainted with the wonderful world of USB sniffers.
