EXTENSIONS FOR USB DRIVER INTERFACE FUNCTIONS

摘要

Extensions for USB driver interface functions are described. In embodiments, input/output of computer instructions and data exchange is managed in a USB core driver stack. A set of USB driver interfaces are exposed by the USB core driver stack, and the USB driver interfaces include USB driver interface functions that interface with USB client function drivers that correspond to client USB devices. Extensions for the USB driver interface functions are also exposed by the USB core driver stack to interface with the USB client function drivers.
