I have a laptop to which I have connected an external monitor and an external keyboard. Now I have replaced my private laptop with the service laptop, I could connect the external monitor, but he does not recognize the external keyboard. With the keyboard and the connection nothing can be wrong, because with the other laptop it works. I tried it again with my own laptop, no problem, nothing is broken. What can this be?

Thanks, I'll test it later, because I've connected the other laptop again.

The USB ports were, because it is a part of the company is software-locked, so that no employee can carry out company secrets.
