I"m new here, and pardon me the my english. What I want to now is: there is some way of th MV to recognize the real lan adapter conected in the notebook? Remenber that the drivers on Bridge and Nat, works very well.
Special thanks everybody to help me.

You can use the features of the real network card by using "bridged networking". Virtual Machines cannot access real hardware directly (USB devices aside), in fact that is rather the point of using VMs, so the real network card will never appear as such inside the VM.

My intention is to test some drivers without to install in real PC's. Thanks.

No, that will not work. The virtual machine cannot access the physical network card directly. The OS in the vm only sees the emulated card in the vm. VirtualBox handles the transfer od data from one to the other.

The driver loaded in the OS in the vm is for the emulated device, not the physical NIC in the physical machine.
