Agree with this, I used MotionInJoy, and was getting frequent bluescreens when plugging in/unplugging the controller. Uninstalled it and am now using SCP and have had no issues since. I think the only real feature missing is the ability to remap buttons?
I'm using a £5 bluetooth dongle from the rainforest, which works perfectly: "Nexxus Bluenano Pro V2.1 Bluetooth Dongle"
