LED operation rules correlating device event, LED action, LED color, and optionally LED brightness are specified in software. As devices connect to a host computer, a correlation between device ID and USB port is detected. A port map for the storage system is used to correlate the location of a USB port where the electronic device connected to a set of LEDs on the storage system. As the states of the electronic devices connected to the storage system change, the custom-defined LED operational rules are applied on the LEDs of the storage system to cause the LEDs identified by the LED operational rules to be illuminated. Since the LED operational rules are customizable, a user can cause any combination of LED action, color, and brightness to be associated with any electronic device state.
