To ensure seamless communication between the ZLG USB-CAN-II device and your computer, you need to install the correct driver. The driver acts as a bridge between the device and your computer's operating system, enabling data transfer and communication. Without a proper driver, the device may not function correctly, or it may not be recognized by your computer.
Official drivers are currently optimized for amd64 architecture. Users on arm64 (like NVIDIA Jetson) may face stability issues, as official native support for these architectures is limited.
