Method and system for providing state change notifications in device drivers

摘要

A method and system are provided for asynchronously providing interested applications of state changes in removable devices. A device driver polls the device associated with the driver for state changes. The state changes result in a change notification being generated. The driver provides the change notifications to the interested applications. The present invention also provides a change notification by a device driver to interested applications when a client application initiates a change in the device.
