A: Yes. Using a 64‑bit DLL on a 64‑bit operating system is necessary for maximum performance and memory addressing. A 32‑bit DLL will still work but is not recommended for new projects. download libusb win64 driver latest version full
MinGW64 : Contains binaries for the MinGW compilation environment (64-bit).
It provides a generic interface, meaning you don't need a specific vendor driver for every single USB device.
