Thanks for your feedback.

With USBGamepad I can play Soul Calibur and Powerstone with those configs. I was surprised at beginning when I noticed it worked without any mappings. I also tried to add values around the ones displayed, obviously with no success.

With PS3(R) I was trying to delete [input]
evdev_device_id_1 = 0 …etc because from what I saw in tutorial video from Floob those lines were missing, but every time I would start a game they would be generated again.
