yes, however certain new instruction that USB3.0 supports will not be backwards compatible. However, most USB 3.0 devices should work in a 2.0 system. To be certified a device does not have to be backwards compatible, so in the end it will be up to the manufacturer of the component as to whether or not they will provide backwards compatibility.

First Generation models ie. those that were released first were fully backwards compatible and played PS2 and PS1 games as well as PS3 games.

yes No you can not turn a PS3 into a Backwards Compatible PS2 game player. That's why the demand for older Backwards Compatible PS3 models with the 4 USB ports has increased the resale value. If you could make a Backwards Compatible PS3 Slim 250 GB why would someone pay as much for an old PS3 with an unknown history that might have been repaired many times.
