Steering wheel that is detected only as a controller

I left to guide me from the positive reviews and ordered this steering wheel. It is true that the workmanship is very good. But to me it is of little if I can not steer precisely to the steering wheel. Even after I put the steering wheel game (Dead Zone) in the PC configuration program on minimal, there was a huge idle (about 15 degrees) before the steering movement began. For me it was an absolute knock-out criterion and the steering wheel is useless in my opinion. Since it can draw much more precise with the normal controller. In addition, the steering wheel is recognized by the controller as a normal XBOX only and not as a steering wheel.
