Windows 7, 2 mice, 1 user, and "Switch primary and secondary buttons" on 1 mouse only?

In an effort to reduce the likelihood that I'll get mouse-related RSI in my (dominant) right hand, I've taken to using an additional second mouse with my left.

I'd like to flip the left and right mouse buttons on just the left-hand mouse, but the Switch primary and secondary buttons option in the Mouse Properties window in Windows 7 applies to both mice.

Does anyone know of a way of achieving what I'm after?

Solution 1:

The following program worked for me, try it out, hope will be helpful for you! Best of luck!

EitherMouse 0.4 - auto switch mouse buttons on second mouse

Solution 2:

Unless your mouse has some proprietary drivers/apps that let you reconfigure the buttons to whatever you want, you can't do it from Windows alone. As you already found, the Windows Mouse properties window applies to all plugged-in and recognized pointing devices. Collectively they will share one cursor and set of behaviors (double-click speed, appearance, primary/secondary, etc.).
