Wish: Manual 'Fuze initiated' USB connection mode

It would be nice if Fuze could be switched to manual mode in which it would not automatically switch to USB communication mode when USB cable is connected to the PC. This way, I would leave it connected to the PC (on my Griffin Doc or cable) have it play music etc. and charge at the same time. In this case connection could be initiated manually by selecting a menu item from the Fuze.
