Methods, systems, and computer program products for abstracting device driver development by layering certain functionality. A driver layer encapsulates device commands and data within a format that is independent of the type of connection between the device and a host computer. Once encapsulated, the device commands and data pass through an intermediate layer responsible for transferring the encapsulated device commands and data to a connection-specific layer. The connection-specific layer then places the encapsulated device commands and data on the particular connection that couples the device and host computer. A single driver layer, potentially provided by an operating system, can thus operate a plurality of devices. Accordingly, hardware developers can be freed from the burden of writing the numerous host-based device drivers that are otherwise required to support an increasing number of connections between devices and host computers, specifically exemplified by improved bus and networking technologies.
