DualSense troubleshooting
Most “dead” DualSense reports on a website are the browser waiting for a button press.
What to check first
Open the PS5 tester, click the page, and press Cross. If the slot stays empty, try USB, then quit Steam’s exclusive mode. Rumble that is missing only in Firefox is the browser. Drift that vanishes when Steam closes is a deadzone. The longer PC setup is the DualSense on PC guide.
- Light bar and adaptive triggers are not Gamepad API features.
- 0CE6 is DualSense. 0DF2 is the Edge.
- Desktop Chromium is the fullest test.
Confirm the reading on the live tester before you buy parts or change firmware. The number on that page is what your browser actually receives.
A practical next step
Repeat the same test after each change and write the resting radius down. A fix that does not move that number did not fix the sensor. If the offset stays above about 0.12 with your hands off the sticks, plan a module replacement rather than another software pass. Model notes live in the controller library.
Frequently asked questions
Does this page change my controller?
No. GamepadTesters only reads the Gamepad API in your browser. Calibration writes, firmware updates, and stick swaps happen in the maker’s tool or at a repair bench.
