Solved it by changing the product id in main.py of avell controll center. The keyboard of Recoil IV has an other id so aucc cant find it. After changing it to 0x6004 it works like a charm.
Just got the 15“ Recoil IV but cant get the keyboard backlight running. With Windows it works well, but everytime I boot Ubuntu, just the arrowkeys and wasd lights up. The avell control center seems not to work for this model. Bios settings also wont affect lighting when booting linux.
Any...
