Windows 64-bit strictly requires all drivers to be digitally signed. If the filter installation fails, you may need to temporarily disable Driver Signature Enforcement:
The filter driver operates by inserting itself as an upper filter or lower filter within a device's driver stack. Using a GUI tool called the Filter Wizard (or the command-line install-filter.exe ), the user selects a specific USB device. This tool modifies the Windows registry to attach the filter driver only to that device. It is important to note that this selection may need to be repeated if you unplug the device and plug it into a different USB port, as Windows can treat it as a new device instance.
Modifying low-level Windows drivers carries inherent risks. Here is how to handle common issues: 1. Accidental Lockouts (Disabled Mouse/Keyboard) libusb-win64 filter installer
If you accidentally apply the filter to your primary mouse, keyboard, or USB host controller, they will stop responding.

The filter installer is a tool used on 64-bit versions of Windows (7, 8, 10, 11) to attach the libusb driver to a specific USB device. Unlike a standard driver installation that completely replaces the existing driver, the "filter" method inserts libusb into the device's driver stack alongside the existing driver.
