There was an earlier thread on this by ratsmooze, and I am having the same problem. I also tried the solutions of entering the run command he/she did, plus changing the custom notification icon to "show." The latter will make the icon show until it is used once, then it disappears again. I went through diagnostics on Norton 360, which found problems with interface and sent me to device manager. I went there and checked if current software were all up to date (yes) and enabled (yes) for human interface/USB hub devices. HELP!
