I keep mine plugged in through USB and use motionjoy DS3 tool to install drivers, then enable it to emulate a 360 controller. Don't know if that helps, but it's what I do and my DS3 works just fine (as long as it doesn't come unplugged ^^

My friend bought a knockoff from Gamestop though, and was able to map keys through joypadder. I borrowed it from him at one point (so I could play wireless) but I couldn't get it to work. So I'd say they work half the time. lol.
