Plug-and-play interconnection system and method with in-device storage module in peripheral device

A plug-and-play (PnP) interconnection system and method with an in-device storage module in a peripheral device are proposed for interconnecting a peripheral device with a host computer unit. The proposed system is characterized by integration of an in-device storage unit with internal functional modules of the peripheral device for storing device specific data and software such as the dedicated device driver of the peripheral device. An enhanced plug-and-play (ePnP) layered structure is proposed based on the in-device storage architecture. The ePnP provides a mechanism to PnP peripheral devices' functions customization. An application of the ePnP is the mechanism to bring up the device driver automatically when the peripheral device is connected to the host computer unit. This auto-installation mechanism provides a truly plug-and-play capability to the user.
