I have 5 different dual shock controllers, and all of them have no rumble. I though maybe it was that all of them were broken, so when I bought my 5th brand new controller it STILL did not work. This makes certain games harder to play (like SOCOM, where hit detection from bullets is a must) So I came to the conclusion that it must be my system.

I'm wondering if this has ever happened to anyone else, and how you went about fixing this problem, or how might I fix it (controller input ports dirty?)

Thanks!
