USB Keyboard & Mouse Stopped Working (Ubuntu 14 LTS)

Question

I've been using Ubuntu 14 LTS on my work desktop, laptop, and home desktop without any problems. Does anyone know what I can do?

What Works:

Keyboard on Boot
Keyboard in BIOS
Keyboard/Mouse on LiveCD
GRUB Selection Menu
Keyboard/Mouse Works on other OS's

What Doesn't work:

Login screen keyboard and mouse

Symptoms:

Stopped working for no apparent reason. (Possibly the built in software-updater changed something)
Internet Message pops up saying cannot connect to internet (Not sure why, works on LiveCD)
Blinking cursor on input field stops blinking after a few seconds.

Tried:

Unplugging keyboard + mouse (Both are using USB 2.0)
Made sure BIOS has Legacy USB Support on
Tried different USB ports
Browsing sites for a solution for a few hours, I cannot find a clear answer.

I have Linux Recovery options with several header versions, I have not tried using an older one. However, I am trying to repair the most current.

3.13.0-32-generic when I choose advanced options to get it working. But 3.13.0-34 does not work with keyboard/mouse (So I cant get to terminal in that state). — JREAM, Aug 17 '14 at 15:18
I hit this booting a 4.9 kernel in ubuntu 16.10. I followed this tutorial to install a 4.8 kernel (from a linux mint live boot), and was able to recover my machine. — Nick Desaulniers, Mar 05 '17 at 06:57

I booted ubuntu with kernel 3.13.0-32-generic (Not the recovery mode), and I did a software update (Software Updater Application) and this seemed to fix it.

I also ran sudo apt-get update

I have no idea how or why this happened, but it seemed to fix it.

I am using XServer for video even though I have an ATI Card
I have not manually downloaded any extra linux kernels.
