You should Turn off Norton Internet Security 2012 in your computer and after that you have to check whether you can see all the devices in the device manager in your computer or not? if can see all the devices in the device manger then it means problem is with related to internet security and if you still get same issue even after disabling or turning off the Internet Security then it might be problem with windows setting. If you can see your computer name in device manger then I will suggest you try these steps first. open device manger and then see whether you have small arrow icon on the left side of your computer name or not? If you have small arrow then click on it and it will expand the device list. In many cases somehow device list gets collapsed. Try this trick it might be helpful for you.
