Abstract
A device driver module for supporting the use of an external device by a computing device which executes an operating system, the device driver module including an initialization portion which is called by the operating system, whereupon the initialization portion detects the presence of a driver plug-in module, obtains information from the detected driver plug-in module, and passes the information from the detected driver plug-in module to the operating system, and also including an operation portion which accesses and executes a functional portion of the detected plug-in module, receives from the operating system an event notification corresponding to the external device and, in the case that the detected driver plug-in module accepts the event notification, passes the event notification to the detected driver plug-in module.
