While this version detected and was useful for my Razer Copperhead gamer mouse, it failed to recognise my Logitech G9, also a gamer's mouse. The G9 could not be configured in any way and only left me with MacOSX's default 2-button operation. It was galling when the G9 was first plugged in to have it thought of by Leopard as a keyboard with the mandatory keyboard indentification process following.

For the same shareware price, the alternative SteerMouse was a better option for both mice. I much prefer the G9 to the Razer so I was forced to uninstall USB Overdrive in favour of SteerMouse. SteerMouse's default settings are fine for the G9.

So while USB Overdrive has been great in the past it needs updating to work with newer products.
