Battlefield 4 problem: mouse and keyboard not functionning

When I tried to play the game for the first time, I was just unable to do so!!! The game launch, I get the image and the sound, everything seems ok. But unpossible to click anything on the screen to select or launch the game. And this for both campaign and multiplayer…

After hours of GPU driver reinstallation, punkbuster reinstallation and other troubleshootings, I figured out that if I plug my XBOX360 controller in, it solves my problem!!!

So, if you encounter such a problem, try to investigate in this direction!
