This has appeared all of a sudden on my 60gb launch date console when I switch it on, controllers don't respond whatsoever even with a usb cable, searched already on Google for a simple solution and all I got was the reset your controller on the back of your pad using a paper clip, this did not work at all and I am clueless as to what to do!! OK if I'm being honest and this might sound daft but my console was OK until MW2 entered my machine, and it was OK until I downloaded the latest firmware update, so I say one of the two are responsible for this, well IMO they are!! (Sony won't admit it will they if I'm right, they don't even release there full failure rate details lol) When I put MW2 in my machine last month my console seemed to struggle with it as if the game was too much for my console to handle, most of the time it would freeze and I had to shut down and restart, before purchasing MW2 and installing the latest update it was working perfectly.. So do any off you lot know what could be wrong or how to get my controllers to work as all four lights blink and when I press the PSP button on my controllers it does not correspond with the console itself!!
