[This video](https://www.youtube.com/watch?v=Aatp5gCskvk) shows an attack where attaching a USB device to a locked computer pretty much takes over all currently running browsers. The trick is that the USB device acts as Ethernet over USB, and a laptop will automatically attempt a connection to such a device.

My work computer has an actual ethernet port, and I almost exclusively use wifi. I do not foresee a need to use 4G dongles and the such. I could mitigate such an attack by merely preventing USB over ethernet from working in the first place. (The alternative mitigation suggested in the video, applying cement to my USB ports, doesn't sound quite so enticing. Additionally, it can be worked around with a docking station.)

How can I do this?
