Der USB Hub hat ein I2C Interface, dies ist aber nicht an den I2C Bus auf dem MBa7x angeschlosssen.
Hintergrund ist, daß über den I2C Bus eine Kundenspezifische Firmware in den Hub geladen werden kann,
wenn keine Daten (Firmware für den Hub vorliegt) dann bleibt dieser hängen und hat keine Funktion.
Wenn der I2C Bus nich am Hub angeschlossen ist dann initialsiert der Hub komplett.
Selbiges gilt für die Pullup Widerstände die im Schaltplan als nicht bestückt eingezeichnet sind.
