The installer typically offers three options:
Select WinUSB unless your application explicitly requires libusbK. libusb-win64 filter installer
libusb is a cross-platform library granting user-space applications direct access to USB devices. On Windows, the original libusb-win32 project evolved to support 64-bit systems through libusb-win64. A key component is the filter driver installer, which: The installer typically offers three options:
This approach contrasts with static driver installation (e.g., using Zadig to replace drivers with WinUSB/libusb). This approach contrasts with static driver installation (e
A filter driver sits in the device stack, intercepting I/O requests. The libusb-win64 filter installer does not replace your existing driver (e.g., a serial port driver for an Arduino). Instead, it inserts a lower filter that allows WinUSB/libusb to coexist. This is critical for devices that need to be programmable (via libusb) but also function as standard HID or COM devices.
Despite the name "win32," this is the standard library used on Windows 10 and Windows 11 (x64) to allow software to communicate with USB devices directly.
