ABSTRACT:
An improved method and system for determining the state of an operating system includes an operating system, a USB host controller that is driven by the operating system to send a polling signal to a USB device, and a management module that monitors the polling signal. If the polling signal has stopped, then the management module takes corrective action to restore the operating system. No specialized software or specialized hardware is required to determine the state of the operating system. The state of the operating system can be determined quickly and efficiently without adding to the costs of the system.
