... If both self-powered and bus powered configurations are possible, a circuit must be provided to switch over power to USB power. An example sub-circuit is given in figure 4, where it is assumed that USB power is used when it is available. To give self-power priority, place T2 so that it switches the USB power line instead. D1 and D2 ensure that the two power lines are not in contention ...
