       - The USB Host Library layer is the lowest public API layer of the Host Stack and presents the concept of USB Host Clients. The abstraction of clients allows for multiple class drivers to coexist simultaneously (where each class roughly maps to a single client) and also acts as a mechanism for division of labor (where each client is responsible for its own processing and event handling).
