not sure if we could help on this. I don’t think there is someone on this board who is using such dongle. But the guide should work because DietPi is nothing else than some scripts on top of a Raspberry OS. But it might be needed to install some additional packages. So you could try installing Build-Essentials (ID 16) from dietpi-software as a stating point. Maybe you will be faced by some issues while compiling about missing other packages.
