iMic does not appear in my sys prefs; very strange

[Eduard Hoenkamp]

I want to use a Griffin iMic, as my old Ti does not have an audio 
input. Under OSX (2.2.4) the systems profile recognizes the iMic as 
one of the connected USB devices. But it does not show up in either 
the 'Sound', or the 'Speech' prefs for the microphone input. The iMic 
hardware must be okay, because it works when I boot my Ti under OS 9 
instead of OSX. At work (also OSX, desktop G4) it does show up in the 
sys prefs. (I already copied the com.apple.sound.plist from there to 
no avail). No answer yet from Griffin. Anyone in the know? Eduard.
