What is the size of code ? I think we need a very small filesystem only.
If we can store 32kB it is enough, we didn't want to store MP3 !

What about pressing a button at boot to switch console ?
e.g if pressed <enter> ==> BlueTooth else USB
Other way: if special flag-file at filesystem is detected, use
