- Calibrate in PurrOS and click SEND TO DEVICE — calibrating alone isn’t enough.
- Move to a USB 2.0 motherboard port (no hub).
- Uninstall and reinstall PurrOS — this has resolved several “sent but game sees raw values” cases; the reinstall triggers a clean firmware update pass.
- Ignore the RAW bar not resting at zero — RAW is the pre-calibration sensor signal; games see the processed output. What the in-game pedal graph shows is what you get.
- Still stuck → open a Discord ticket with videos of the behaviour in each game.
