Nacon controller not detected
If the operating system’s controller list is empty, the website cannot see the pad either.
What to check first
Many PC pads speak XInput in one mode and DirectInput in another. DirectInput often arrives with a non-standard mapping. Use the generic PC page, switch labels to numbers, and press one button at a time while you watch the raw list. That tells you the pad is alive even when the letters look wrong.
- Try the maker’s XInput mode on Windows.
- Press a button after the tab is focused.
- A remapper that grabs the device exclusively will hide it here.
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.
