@janmilpol… That sounds familiar. I seem to recall someone earlier in this thread mentioning it worked for them. Although, now I don’t think the custom kernel is needed. It’s only the cmdline.txt that needs to be done for those controllers.
@sduckie2…. I don’t see a controller listed there… Or at least none jump out at me as being a controller. That ID you see there is what would need to be added to cmdline.txt
