I already moved your old topic to correct forum. Mark this as duplicated.

Devices that use CH340 driver not showing up on jetson orin nano

I don’t know what you are doing. Obviously you are installing a driver from a very old kernel to newer kernel. Of course it will fail. Maybe you should start from learning how to build kernel first. https://docs.nvidia.com/jetson/archives/r36.3/DeveloperGuide/SD/Kernel/KernelCustomization.html
