The regular iPods like in the photo are USB mass storage. Its just the iPod touch, iPad and iPhone that need the special USB mux driver and apps that talk over it.

If your app knows how to then it can talk to the Apple File Connection service for limited access to the media area of iPod touches, iPads and iPhones.
