Hi everyone. I just got myself some Logitech USB headset 350, and can't seem to get them to work. Intel Mac, 10.4.8. The computer "sees" them in the USB tree, but not in the Sounds section of Prefs, or when accessing the Audio Midi Setup, which was a workaround suggested to me by a very savvy Mac friend. I've tried different USB ports, including the ones in a powered hub. I've verified and repaired permissions, logged out and gone into the Administrator account and tried there, no joy. Restarted the machine a few times, no joy. The really odd thing is that when booting into WindowsXPpro on this machine, they work perfectly fine, no fiddling, just plug em in and use em. Is there a hidden pref I need to be accessing, or a plist somewhere that could be deleted, to rebuild when rebooting (did that even make sense?? )? Here's some screenshots of what I'm talking about: Many thanks in advance for any and all suggestions!
