I don’t think the issue lies with the firmware. I had a similar problem. The launcher doesn’t show a ban, but when you start the game, the loading screen displays, "You are currently banned...".
I can’t say for certain what the cause is, but Kmbox is detected. I wouldn’t use it anymore. There are many complaints about Kmbox detection. The issue with Kmbox is that the driver is detected. Additionally, the VID and PID of the gaming mouse and the Kmbox are not identical (these are essentially the ID of your mouse device). That’s why Kmbox gets detected.
The solution in this case would be an Arduino Leonardo or a Teensy. With these devices, the VID and PID of the mouse and the Arduino are identical. That’s why they can’t be detected. However, obtaining and setting them up is significantly more complicated.
One possible reason why you don’t have a launcher ban but see that message only on the loading screen could be a typical EAC/BE ban. You can also get banned if you have inhuman stats (headshot rate, accuracy).
I believe that’s more likely the cause of your ban.
Try experimenting. Spoof normally and try playing without Kmbox. If you get banned again, then the issue probably lies with your DMA firmware.
