These identifiers are actually driven by the upper-levelProgram(Usually a bus driver), which is used by the Windows system to find and load the correspon
USB devices are very complex and consist of a number of different logical units, and the relationships between these logical units can be described simply as follows:
L devices (Usb_device) typically have one or more configurations (Usb_host_config)
L configuration usually has one or more interfaces (Usb_interface)
The L interface usually has one or more settings
L setting has no or more than one endpoint (Usb_host_endpoint)
