That is brilliant!

I have had a number of bad experiences with Dell's tech support in the past and it sounds like you may have too NightGod.

As you may know, their optiplex systems only accepts USB mouse and KB, well one time as their tech support person read me diagnostic steps from a webpage to try and remidy a non functional mouse, they instructed me to delete the USB root hub and all other USB related items from the control panel. I asked them "how will the keyboard be able to respond if we delete this?" and they told me it would be fine. Guess what, it wasn't. They ended up replacing the MoBo and mouse.  ;D

Also, there is some kind of recall for their MoBo's right now, something to do with popping caps near the cpu. If you need a MoBo for a Dell system, there is a long wait for em because of this.

My Happs 3" trackball died on me suddenly as well (Unrecognized USB device, yadda, yadda, etc...) a few months ago right after a thunderstorm. Luckily SlikStik replaced it for free (Mighty Big of them) but I have heard that unless you ground the trackball with the supplied ground wire, they have a "Glass Jaw" when it comes to powersurges.

Insta-Frenchfry.

Just sharing my woes.

GL on this.
