Here is everything you need to know about understanding, installing, and troubleshooting the libusb-win64 filter driver. What is Libusb-win64?
To use libusb on Windows, your target USB device needs to be "attached" to a compatible driver like libusb0.sys (used by the original libusb-win32 project). While you can completely replace a device's existing driver, this can break functionality for other software that depends on the original driver. The filter driver approach offers a more elegant solution: a filter driver sits in the driver stack for a device, intercepting communication between the application and the existing driver. This allows libusb-based applications to access the device while retaining full functionality for other programs that rely on the original, built-in driver. The core library used to achieve this is the libusb-win64 filter installer, which is part of the libusb-win32 project that provides 64-bit support.
