Take, for example, a recent call we received. Someone called with a question about their recently purchased PDP Afterglow AP.2 controller. It's a great controller; I reviewed one a while back (link below). However, it seems that this gamer purchased one used that only included the controller and a USB cable. The AP.2 is rechargeable and this cable can be used to recharge the battery, but isn't used to sync the controller to your system. There is a button near the USB port on the controller that is used to sync-up the controller to its USB dongle, but without its dongle, an AP.2 controller will not work. This is actually the case for almost all PS3 gamepads that aren't made by Sony. The only exception I've ever reviewed is the Subsonic NEO (link below), which I assume uses some form of dark magic to connect to the PS3 without a dongle, since the Sony Corporation frowns on that.
