Doesn't anyone have any idea, or even care about this device? I can't 
find any Conexant chip in there, unless it would be inside the tuner.

If nobody cares about it (I see only one secondhand Airstar USB on eBay 
and it looks different from mine), I'll sell mine and forget about it. 
Otherwise.. Please post.
