I don't know much about those two controllers in question. I do know about the wired X360 controller.
Anyway concerning the wireless 360 controller it's supposed to work once you plug in the USB dongle or what have you for windows to recognize your device, and as long as windows does recognize your device then PGP will detect it. When you open up PGP your wireless X360 device will be seen in PGP and it will go through a button, trigger and analog stick test to make sure everything is functioning.
When its finished detecting, PGP is now ready for emulating your game in this case
Mass Effect 3. If it is not emulating or receiving any signals from PGP to emulate the kb & mouse then you need to start PGP as Administrator.
