The DualSense controller can now be updated directly from Windows, without players needing to connect to a PS5.

PC players can now update their DualSense wireless controller with the latest firmware from Windows 11 and select Windows 10 devices, without connecting to a PS5.

Connect your controller to another PS3, or connect a different PS3 controller to your PS3 to make sure the problem isn't with the console itself. Check the USB connection.
