Ok, so I have a Ps3 controller and it wouldn't work for a while, so then I used a usb cord and hooked it up, then pressed the reset button, now my controllers won't work without being hooked up to the usb cord, any help?

I had this exact problem if you set up the ps3 correctly and they don't work this is what I did
I had too go to system settings go to restore ps3 system that's all I had too do make sure whatever u did make sure its saved on a memory card unless u want everything craped up

A physical memory card or an internal memory card?
