mapping mouse buttons on logitech mouse

I have a Logitech G5 mouse that I love and I use it on my mac mini. The only issues is I can't map the buttons. I want to be able to map the back button to actually work. Any way of doing this? Thanks

Get Steermouse.

Dumb question - are there no Mac OS X drivers for it? That would seem to be the obvious answer, no? I am using a Logitech S530 keyboard/mouse set and the drivers seem excellent. All buttons work as advertized. GREAT product, the S530 set.

nope no mac drivers for it. Is there any free solutions for this. Sorry I am cheap

There was a link I saw in one of the forums for a chance to win a free SteerMouse licence. Just do a search, you should find it.

You don't need drivers, you just need Steermouse to configure it. And don't under any circumstances, install any Logitech software on your Mac.

Steermouse is only, what $20? Don't you have some relatives to sell?
