USB Logitech Desktop Microphone

[blittle2 at nyc.rr.com]

Hello,

I have a USB Logitech desktop microphone. I'd like to use it for 
recording podcasts using Audacity. The same microphone works on Windows 
and Mac without installing any kind of driver. But I don't want to work 
on Windows and mac. I've come across a couple of sites that refer to 
either editing or recompiling certain files, but I don't know how to 
start or where to even find these files or what they are named. In 
other words I'm still very much a newbie when it comes to recompiling 
driver files to get things to work.

What I have:

1.A G3 Blue and white "Clamshell" iBook
2.I am working with Ubuntu 6.06
3.Audacity
4. I work in the Gnome desktop environment
5. I know basic linux commands and can get around pretty well in the 
command line.

Thanks
