Sorry Saturn I might be wrong I do understand that the latest version of cleven works with kp49 and old injection drivers and kp50 with new injection drivers installed but what I understand that rayon has is (a mix of) kp50 with old wl1251 injection drivers and this is why he gets the error. As you can see from his previous post he only copied the new drivers in opt/cleven/compat-wireless-v1
