I have the a problem with my wireless controller, it is not being detected by the console. I've change the batteries, but still it doesn't work ( the circular LED keeps on blinking ). I works fine with the cable.
There's a small button on the top right corner of your controller. Above the right LB and LT buttons. You'll see the same kind of button on your console (below the memory card). Press and hold both button simultaneously, for a couple of seconds.
