I am not sure where you're going with this. User-space software only
interacts with a device using a driver, and only interacts with that
driver, at the lowest level, using I/O operations like ReadFile,
WriteFile, DeviceIoControl, etc. You could write a driver to simulate
a device but you don't need any USB functions for that.
