HEX-USB+CAN Interface on different cars

Ok, but yours is a reader, the cool thing about the VAG-COM is that you can also reprogram things in the car, and considering the cable that comes with it is just a cable, I would imagine there might be software/drivers out there, comparable to VAG-COM but that can be used on other vehicles, since VAG-COM was made to work only on VW and Audi. We'd like to be able to do some reprogramming on the car too, of course this is all a project that would be nice to get going but who knows?

Ideally we'd like to get it working on any car, the Yaris would only be a guinea pig (hey! it actually looks like one ).

Correct. There are VAG Com type tools out there for Toyota vehicles (including Toyota's own Techstream tool), but they are mighty expensive ($1,000+). The key is getting ahold of the protocol specs. OBDII is an open standard, so when I made my reader, I bought the SAE manuals for the protocol. The Toyota protocol spec seems to be one of those super-secret things...
