I am wanting to use a PS3 controller for emulators like PCSX2. When I plug in my PS3 controller with all of the necessary drivers while fully function and the USB installs drivers which function properly, my controller still isn't turning on. In my Drivers, I see under "Unspecified", "PLAYSTATION (R) 3 CONTROLLER". Is there a way to turn on my PS3 controller without making it go to my console?
Motioninjoy is a risky tool to use - it works well most of the time, but it spawn its own Internet popups and can generally be a pain to maintain. You will need to run Motioninjoy each time you unplug and replug the controller as well. Furthermore, if you leave your device plugged in and Motioninjoy running, blue screen crashes can occur when trying to put a computer to sleep, and sometimes during shutdown.
I have personally had better luck doing things manually, following this tutorial. It walks through step by step what to do. Essentially, it fools the computer into using Xbox 360 controller drivers with a PS3 controller.
