Make sure they are PS3 games before you look further
The old PS3 can only play the oldest PS3 games. A new PS3 can play both new and old games.
No you can not get a chip, the PS2 could not read PS3 blue-Ray game discs and could not play them if it could read them. A PS3 is the only game console that can play PS3 games.
Having a PS3 with only 2 USB ports will cause it to not read PS2 games and having DVD's from a different region than the PS3 will cause it not to read them. I'm not saying that is your problem only something you need to check. All PS3 models play PS1 games and they all play PS3 games which I've heard do not have region codes.
