"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?

This is the Audacity help forum. We have no connection whatsoever with the GMX4 mouse device and do not provide technical support for it.
prinsoscar, please refer to the manufacturer’s website, or to the retailer, or both, for support with their product.
