I have already read Sony's online controller troubleshooting guide, but the vibration function is not working with any of my three playstation 2 dualshock 2 controllers. I put away my ps2 for a while for my ps3, and i just set it up again. I tried many games that all support vibration and that used to vibrate (all of these games had the 'vibration function: ON' setting). Any ideas of what is wrong. please, any help is appreciated.
