project64 1.6 USB Controller Configuration.

I have project64 working and the games, but how do I configure the USB controller?
I'm new to this stuff, so please be patient. :-[
The controller works when using epsxe.

Connect your USB controller before opening up Project64. Then go to Options>Configure Controller Plugin, and on the drop down list, select your device and just configure the buttons normally, and make sure that "Controller is plugged in" is check marked.
