Patent ID: 7996580

Claim:
A system comprising: a) a host device, the host device including an interrupt controller for handling interrupts; b) a slave storage device interfaced with the host device; c) a power source for providing a current to the slave storage device; and d) an electrical activity monitoring module interfaced with the interrupt controller and the power source that provides the current, the electrical activity monitoring module determining a correlation between different operation modes of the slave storage device and respective electric current requirements by initiating a test procedure to probe the slave storage device, the electrical activity monitoring module monitoring the current and sending a notification to the interrupt controller regarding a change in the current between current levels correlated to different operation modes, in order to prompt a response from the host device, the response including conditionally activating a polling application from an inactive state on the host device to initiate communication with the slave storage device without waiting for the polling application to poll the slave storage device, the polling application configured to periodically address the slave storage device when active.
