My PS3 won't reconize any of my controllers, putting the cable in works, it find the controller, but when I unplug te cable the lights start blinking again and I can't use the controller, what to do?

Hmmm. It sounds like either your PS3's Bluetooth controller is on the fritz, or all of your controllers are on the fritz. Since I doubt ALL of your controllers are malfunctioning, I am betting it's your PS3. I suggest having a friend with a working controller stop by and test his controller against your PS3. IF your friend's controller works, then you know that the PS3's Bluetooth controller is working.

Second step is to check to see if the USB cable is transmitting a trickle charge to the controller. Again, using your friend's controller (make sure he brings his own USB cable with him), try charging his controller with HIS cable first. If after 10 minutes of playing with the controller plugged into the PS3 via USB, you unplug it and the controller still works, then the problem is most likely your own USB cable (it's apparently damaged in some way). Now run down the controller's battery and try recharging it with YOUR USB cable. If it fails to charge, then you know that all you need is a new cable. Just in case, make sure you test EACH of your USB ports. A simple replacement will cost you around $10.

Otherwise, your PS3's UBS port(s) are not properly working and you should send in your PS3 for repairs. As stated above, test each of the USB ports on your PS3. My 60GB one has 4 USB ports, so I would test all 4 of them before sending in the PS3. Then, if you want it repaired, make notes of which port(s) is(are) malfunctioning and send it to an authorized PS3 repair center.
