How to make USB optical mouse work with MacBook Air? I just bought a MacBook Air and a cheap Leadership USB optical mouse, which I can't get to work with the MacBook. It works fine with Windows and Linux, and the Macbook Air USB ports are fine. I checked it with USB drive and a Microsoft mouse without encountering any problems.

What can I do to solve the problem?
If it supports the standard USB mouse functionality (HID), it should work.  Otherwise, you can use SteerMouse or USB Overdrive.  If you have the Developer Tools installed, you might also see what USB Prober says about the device.
