Before diving into the installation, it is critical to understand why this is difficult. The JAF box is a USB-based hardware dongle that communicates via a proprietary protocol. The original drivers were developed during the Windows XP/Vista/7 era. These drivers rely on low-level access to the system’s USB stack.
When Windows 10 arrived, Microsoft made two major changes:
As a result, a standard installation will fail. You will see an error message: "The third-party INF does not contain digital signature information" or "Windows cannot verify the digital signature for this driver."
For some JAF clones or newer revisions, the original INF file won't work. In this case, we can use an open-source tool called Zadig.
Warning: Using libusb is a workaround. The official JAF application may not fully communicate with the box. Test thoroughly.
