A. For using any code from GitHub:
1. review the current open issues ... you may find you are dealing with something that is already known.
2. read/study the documentation ion the Wiki: WinUSB has the following links in the Wiki [

Online library reference
Documentation
INF template
3. Consider raising an issue on that Git repository if you think there is an error caused by its code that you can describe clearly..
B. You need to give us much more information about your problem:
"But got confused with notifier." What does that mean: was there an error ?
"I have 4 windows." Okay, what are they; what do they do.handle ?
Post more information by editing your original post. Remember, we can't read your mind.
