[AG-TECH] USB microphones not working in Linux

[Anton Gerdelan]

Hi,

I'm using a ClearOne 50 USB microphone/speaker under Linux.

RAT can detect it, but it dosn't interface properly, so it won't work.
Under Windows the same microphones work fine.

Other microphones (3.5mm jack-based) work fine with our Linux AG machines.
I've tried this on different Linux flavours (FC6 and Kubuntu E&F) with KDE and 
Gnome (ALSA and ARTS) and they all have the same problem.
I've tried other USB microphones (logitech camera mic) and they don't work 
either.

Would it be helpful if I supplied a log or debug message output? (if so which 
one?).

Any information appreciated,
