1. A machine-readable medium having stored thereon as a computer program for execution by a processor and a monitoring logic for automatic device plug-and-play without user intervention that is implemented as a state transition system comprising:

  • a first state in which a device driver is not installed and a plug-and-play identifier has been detected from a device connected to a port;

    a second state in which the device driver is installed and the plug-and-play identifier has been detected from the device connected to the port;

    a third state in which the device driver is not installed and the plug-and-play identifier has not been detected from the device connected to the port; and

    , a fourth state in which the device driver is installed and the plug-and-play identifier has not been detected from the device connected to the port, wherein the states are transitioned among one another based on a set of transitions comprising;

    a first state-to-second state transition based on a device driver installation event;

    a first state-to-third state transition based on an event of no detection of the plug-and-play identifier, a second state-to-first state transition based on a device driver uninstallation event;

    a second state-to-second state transition based on an event of detection of a new plug-and-play identifier;

    a second state-to-fourth state transition based on the event of no detection of the plug-and-play identifier;

    a third state-to-second state transition based on an event of detection of the plug-and-play identifier;

    a third state-to-fourth state transition based on the device driver installation event;

    a fourth state-to-third state transition based on the device driver uninstallation event; and

    , a fourth state-to-second state transition based on the event of detection of the plug-and-play identifier.
