| Issue | Solution | |-------|----------| | Controller lights up but no input | Open joy.cpl (Run → joy.cpl ). Check if it appears. If not, reinstall USB root hub drivers. | | D-pad moves character instead of menu | The game sees the D-pad as buttons. Use Steam Input to remap D-pad to "Left Stick" or "Directional Pad" mode. | | Vibration not working | The QHM7468-2VS often lacks true force feedback hardware. If it does have motors, x360ce or Steam Input can enable it under "Rumble" settings. | | Controller disconnects randomly | Try a different USB port (USB 2.0 is more stable than USB 3.0 for some older controllers). Disable USB selective suspend in Power Options. |
