Unknown device in device manager

[Mzmkont]

Hello,
I noticed that there's a unknown device in my device manager. As I know It's my mouse. Razer DeathAdder. But why is it showing like an unknown device?
Is there a way to fix this problem?

Thank you.

Install the chip set driver used for the mother board.
Or if you have not installed the driver that comes with the Razer Death Adder do so.
It may be because you do not have the usb 2.0 drivers installed in windows.
Or if the board supports usb 3.0 ports then that driver is also not installed in windows.
