Well, I finally plugged in my mouse the other day, and today I didn't have it in and noticed DesktopConsole (system.log) showing the following:

Etc, Etc... It just keeps going... I had an incling that it had to be the mouse and the software waiting for me to plug it in, but jeeze, it has to grind for half a second for each one of those entries... It doesn't screw performance, but it's an incessant noise. Any idea how to get it to not do that when the mouse isn't plugged in? Thanks in advance.
