Does anyone have some instructions for hooking up the PS-ON pin? I'm trying to use the PS-ON pin on my RAMPS board, however I've run into an issue. When I flip the switch on my PSU, nothing happens. Its not until I "jumpstart" the system with USB power will the PSU stay on. I've hooked the green wire from my PSU to the PS-ON pin, and the purple VSB wire to the 5V pin next to the PS-ON pin, however that doesn't seem to adequately power the Arduino. I have a feeling I'm missing something obvious, any suggestions?
