I think that was the right approach for the first controller. It is one of the worst controllers for traditional controller games, but it’s the best by a long shot for mouse driven games. So when you plug it somewhere that doesn’t have the correct drivers it’s more likely that you want to use it as a mouse than as a controller. There’s an open source driver for Linux (or at least there used to be), but I don’t think it ever got ported to Android since I guess it would require a rooted phone.
