Sebastian Zagrodzki 5f122b4dcd Introduce two more layers between device and endpoint:
device -> active config -> claimed interface -> endpoints.
Device can have at most one active config. A config can have
multiple claimed interfaces, each with a specific alt setting.
An interface with an alt setting defines a list of endpoints.
