I'm running Mountain Lion on a 2012 Macbook Air and am having real problems with USB mice. I have a Logitech MX Revolution and the tracking feels inaccurate and uncontrolled. I have tried Steermouse and this improves thing slightly but it's still terrible compared to in windows. I have purchased a Logitech MX Performance and this is identical. Another cheaper Logitech mouse which is wired is slightly better but still lacks accuracy. Is this a Logitech issue or are non-apple mice in general like this with Mac OSX?
