I keep on getting "Controller not found" and it's ruining my entire PC


This is what pops up. It disconnects my mouse even if the game isnt on. I NEED a way to stop it. It’s ruining EVERYTHING I do on my computer

Here is what it looks like. Anytime my mouse is not moving (you can see it hovering over those locked techtree vehicles), its disconnected and I can’t to ANYTHING. It’s a pain for gaming, for my fucking work and for anything inbetween. i’ve tried some stuff, nothing worked. I geniuenly need help

If the mouse disconnects even while War Thunder is completely closed, the game is very unlikely to be the root cause. This should be treated as a Windows, USB-controller, power or physical connection problem first.

Please test in this order:

  1. Connect the mouse directly to a different motherboard USB port, without a hub or front-panel extension.
  2. Test another mouse or cable on the same port.
  3. In Device Manager, check the USB controllers and HID devices for warning symbols or repeated reconnects.
  4. For USB Root Hub/Generic Hub devices, temporarily disable Allow the computer to turn off this device to save power and test again.
  5. Check Windows Event Viewer around the exact disconnect time for USB, HID or driver errors.
  6. Close hardware/RGB/controller utilities one at a time to identify software repeatedly resetting the device.

The exact title and publisher of the ‘Controller not found’ dialog would help identify which application is producing it. A short video is useful, but the Event Viewer entry and the affected USB device name will be much more diagnostic. I would not reinstall War Thunder unless the problem occurs exclusively while its process is running.
