 * a PWM generator power source by logical name, no error is notified: the first instance
 * found is returned. The search is performed first by hardware name,
 * then by logical name.

 * If a call to this object's is_online() method returns FALSE although
 * you are certain that the matching device is plugged, make sure that you did
 * call registerHub() at application initialization time.
