Modern versions of Windows (Windows 10 and Windows 11) strictly require digitally signed drivers. Because version 1.2.6.0 is older, its digital signature may be expired or unrecognized by modern Windows Kernel-Mode Code Signing policies. You may need to disable Driver Signature Enforcement during testing. 2. Legacy vs. Modern libusb

Developing USB-integrated software on Windows requires low-level access to USB hardware devices. The package provides the necessary development headers, libraries, and filter drivers to communicate directly with USB hardware without writing custom kernel-mode drivers.
