ABSTRACT:
A data storage device activity state is sampled and used to control a remote data storage device activity indicator. A disk drive activity signal is sampled by hardware either based on an edge transition of the activity signal, or on a periodic basis. If the state of the activity signal changes, state change data is sent via a controller to a keyboard. A disk drive status light on the keyboard is controlled by the change data. The controller is a USB host controller that sends the state change data to a USB function that controls the status light.
