How to Enable USB Debugging on an Android Device

Link to the Written Procedure/Downloads for this Video:

You've probably heard of USB debugging more than a few times if you've ever looked into rooting an Android device. Essentially, this feature found in all Android devices (even Android Wear, by the way), allows the device to take commands from the computer it is connected to (via USB as the name suggests). Once this is enabled, you can use the SDK and/or ADB (Android Debug Bridge) to then tell the device to install and run test applications, flash/erase/backup certain parts of the device's memory, and more. What we, and what you probably see it used for most though, is to allow us to then run commands to gain root access on said device, flash a custom recovery, or something else similar.

Regardless of the reasoning, here's how to enable USB debugging on any Android device.
