Thank you for your question and reaching out.
I can understand you are having queries related to libusb driver .inf installation.
Please check the bin directory and run inf-wizard.exe. Here is where you can customize and generate an INF installation file for your device, as well as the installer executables. Select the same bin directory you are running from to place the output of the tool (so that the INF file is next to the x86, amd64 and ia64 directories).
Now you can run the installation executable. You can also go to Device Manager and right click your device and choose "Update Driver Software" and point directly at your generated INF file. At this point your device should be loaded.
Also you may reach out to GitHub community for pyusb and libusb for additional steps or still issue persists.
