Abstract
A system for connecting an external device and a host system includes an input/output code element on a host system linked with the external device. The input/output code element generates a device identification string. The device identification string includes an optional feature component associated with the external device. The optional feature component indicates at least one extra feature that is included with a particular external device, such as an envelope feeder for a printer or an audio component for a wireless Internet appliance. The system further includes an installer linked with the host system. The installer receives the device identification string and parses the string for the optional feature component. The installer creates an add-on identifier key in the host system's registry based on the optional feature component. The system further includes a device driver for operating all features of the external device identified by the device identification string, especially the optional feature component. In particular, the device driver accesses the add-on identifier key in the registry. The device driver includes a device driver configuration component which is modified in accordance with each add-on identifier key to include features associated with the optional feature component.
