Hardware change off brand ps3 controller?

[mrissaoussama]

i got 2 of brand ps3 controllers, the problem is that they can't be paired together at the same time. when th second one connects, the first onez is disconnected. i tried a variety of cable/wireless combinations and port placements. and that's how i thought that the controllers have the same "info"/mac address. so i thought if there is any homebrew on ps3 or program on pc that lets me change the controllers' info so they could be paired together
