Abstract

One or more custom device drivers for a peripheral device may be installed from the peripheral device onto a host computer. Upon connecting the peripheral device to the host computer, an operating system of the host computer is exposed to a default configuration of the peripheral device that contains only a device driver class interface or interfaces for which the operating system includes preinstalled class level device drivers. The peripheral device then receives an install command from the host computer, and automatically transmits one or more custom device drivers from the peripheral device to the host computer. In response to receipt of a change command from the host computer, the configuration of the peripheral device is changed to an alternate configuration that includes interfaces for the custom device drivers.
