NOT A HARDWARE FAILURE (good news.)
Hint: The common upperfilters, lowerfilters issue. Many posts about that.
All of a sudden Windows XP does not recognize the CD ROM (Lite-on LTN486)installed! Have uninstalled/installed hardware, but CD still does not work. After going through the troubleshooting progress got the error message "cannot find hardware device (code 41)" does anyone know what this means and how can I fix it..
Thanks for the help!
