DavidYerger, The problem you reported seems different than the bug reported by Raphael. Your problem is that no external PS/2 or USB mouse seem to work, while the bug reported by Raphael is that the scrolling function of the touchpad stops working when connecting PS/2 mouse on boot. It is better to open a completely new bug report with the information from https://wiki.ubuntu.com/DebuggingTouchpadDetection to avoid confusion.
