I was having trouble getting the Fanatec csldd to be recognized by farming simulator 22. In the inputdevices folder they have a file that looks for the podium dd1 but not the csldd. I made this to be able to get your csl dd detected in the game when in normal (red) mode. The file goes into the documents/mygames/farmingsimulator2022/inputDevicesManual folder. You will still most likely need to manually setup your buttons and adjust the deadzone to get it all up in running but this should make life easier.
To install unzip it, and then put the file into the above directory.
