I've got a *boat-load* of Logitech devices I've been using for years - love them, since they generally "just work" right off the bat with any OS.

But what I'm wondering is if there any tool that I can use to tweak the devices a little - eg my TrackMan Optical or additional buttons/keys on some keyboards.

I do believe that they're releasing some sort of Control Center for other OS's - something I'd like very much.
I know I can configure the devices manually in the X config, but that's a real PITA.
