You can find pre-built 64-bit binaries (MS64 for Visual Studio or MinGW64 for MinGW) on the libusb GitHub releases page . 2. Use the INF Wizard (libusb-win32 legacy)
In summary, the 64‑bit libusb driver provides a seamless, high‑performance bridge between user‑space applications and USB hardware, leveraging the advantages of modern 64‑bit operating systems while preserving the simplicity of the libusb API.
On Windows 10 and 11 64-bit, unsigned drivers are blocked. If you manually compile an old version of libusb0.sys or libusbK.sys without a digital signature, Windows will reject it. libusb driver 64 bit

Click the large or Install Driver button. Zadig will automatically generate a self-signed certificate, install the 64-bit driver, and associate it with your device's Vendor ID (VID) and Product ID (PID). Troubleshooting Common 64-Bit Libusb Issues Issue 1: "Driver is not digitally signed" On Windows 10 and 11 64-bit, unsigned drivers are blocked
If you're developing a commercial product, note that libusb-win32 based drivers can be submitted for Microsoft WHQL testing to eliminate driver installation warnings. However, the current Windows Logo Kit license lists GPL as an "excluded license," so WHQL submission may not be possible without dual licensing.
If you are actively developing hardware firmware alongside your libusb software, conduct your initial deployment inside a 64-bit virtual machine (e.g., VirtualBox or VMware) to isolate your host OS from potential kernel panics.
