USB ports were brought about in an attempt to standardize how we plug devices into a computer. Computer mice, keyboards, digital cameras, and many other electronic devices now utilize an USB port connection. A port that is not functioning as expected can be mission critical, or an infuriating annoyance at the least.

If it's dozing off is not in your best interest, you can disable this feature.
