"USB-units deactivated - reactivate through unplugging

I just bought a GMX4 mouse and using a Macbook Pro I installed but upon plugging in the mouse through the USB slot the computer gives me a warning pop-up saying “USB-slots deactivated. Reactivate USB-units by disconnecting the unit now connected” (refrasing from swedish). How do I use the mouse if this happens and how come it does happen?
