Hello Richard ,
Appreciate your attention. I managed to solve the problem. In fact , he was direct flashing 3 colors ( blue , red and green ) when connecting the PS4 console.
I decided removing all cables ( Joystick, Keyboard and Mouse) and connected only the Cross Hair ( being white) . After I was putting other cables and solved the problem. From what I understand , I was having a compatibility problem and I doing it , as if he had a RESET in CrossHair .
Sorry for my english , I 'm not very good .
Thank you again and thank you for your attention and speed in trying to help us.
