This problem has a bit of a back-story, and I will also sum up the steps I have taken to attempt solving it.
1. I installed Ubuntu 9.04 within Windows Vista (on Dell Inspiron 1520).
2. I moved from IL to CA.
3. When I finally received all my computer hardware (some shipped), mouse and number pad were not working. Windows did not even recognize that anything had changed when I plugged them in.
Note: *Two External hard drives ARE working.*
4. Figured the mouse was shot (very old), bought a new one. This also produced no effect in Windows.
5. Thinking my Ubuntu install had screwed with some drivers, I uninstalled Ubuntu and restarted. This produced no change.
6. I then used System Restore to go back before the Ubuntu install; upon restart, I could no longer boot Windows without a blue screen.
7. I ran diagnostics, and came up with an error:
DST Short Test
Error Code 0148
MSG Error Code 2000-0148
MSG Unit 0:1DE Error:
Status 3E No additional sense information
8. This error led me to believe I had a hard drive failure. I then reformatted, but used Ubuntu because I did not have my Vista CD with me.
9. After clean Ubuntu install, input devices still did not work, but everything else was working fine, no more blue screens. (I did multiple updates and driver checks to make sure my input devices were supported in Ubuntu.)
10. For kicks, I downloaded Windows 7 from my developer's account, then did a clean reformat. Again, everything works fine, but input devices (mice, keypad) have no effect.
11. I ran diagnostics one more time, and received no error.
My attempts to fix this have included:
-Uninstalling/Reinstalling all USB modules in Device Manager.
-Removing battery and unplugging computer, left to sit overnight.
-Using different USB ports.
-Using a USB Hub.
-Updating all drivers, bios, and chipset from Dell.
Please bear in mind that, through all these steps, USB storage devices (hard drives, iPod) have all worked just fine.
Thanks so much for your help.
