Hello. There was a problem with the drivers. More specifically, the Universal serial bus (USB) and some unknown devices. At the same time I can not connect my mobile via USB. When I update, to find herself, he either finds it, but downloads but fails to install it because he is denied access or does not find anything. For this USB i tried the drivers from CD to MB but it was a mistake and bye. Plus, I can not even uninstall the device. The problem occurs both on the front and rear USB sticks.
I attach the screen.
I do not know the advice. For any help I would like to thank.
