A specialized driver that supports advanced features like isochronous transfers (streaming data) and can be used if WinUSB has limitations. libusb-win32 (Legacy):
is a cross-platform, open-source library that allows user-space applications to communicate with USB (Universal Serial Bus) devices. Unlike traditional operating system drivers that run in the kernel (which requires high privileges and can crash the system if faulty), libusb provides a portable API that applications can call directly. This makes it an essential tool for developers working with custom USB hardware, such as microcontrollers (Arduino, STM32), FPGA programmers, radio peripherals (SDR), or specialized lab equipment. libusb driver 64 bit

Microsoft's official generic driver. It is the most stable and natively supported option for modern Windows (10 and 11).
