libusb initialization crash

[SherifOmran]

when i tried to use the libusb from the following link
https://github.com/libusb/libusb/wiki/Windows
I found that the app crashes upon tying to initialize the library.

I am trying to use the usb port directly to send some special commands to it through hid

any help is appreciated

@SherifOmran you may need to improve your post, by providing more details.

What compiler are you using?
Did you download pre-built binaries from the libusb project?
If so, are you sure they match the compiler you're using?
Are you able to build and run the examples (non Qt apps) provided by the libusb project?
Eventually, show the code snippet where you initialize the library
