Use unsupported USB footswitch? I am attempting to use this footswitch:

They only support windows, and USB Overdrive apparently doesn't support it either.

I want to use it to click the mouse in OSX.

Is there a software that will allow this configuration?
Runs the setup software under Windows. The pedal stores the settings itself.
