I think you are taking the wrong approach. If you just want to create
a libusb compatible layer that sits in between your application and your
special driver then you should not care about the internals of the current=

Windows implementation.

All you have to do is to implement the API functions specified by usb.h.
If I had to do the job I would use windows.c as a starting point, remove
all platform dependent code, and reimplement this code from scratch.
I think this is much easier than trying to adapt the existing code to your=

driver.
