I'm trying to fix a problem on a Vista machine where all the USB ports seem to have power but they don't recognize devices plugged into them.
It seemed to start after I plugged my mp3 player (sansa clip) into it and disconnect it. So it sounds similar to this article http://support.microsoft.com/kb/817900 but that was for XP. And I did try all the fixes (including the registry entry) but they did not help.
It also sounds similar to this SU question 50110 but I don't think it is the mother board.
I have see other places that suggest reinstalling the OS...but that seems like a last resort type of thing. I have also seen a suggestion of doing a system restore but not sure if that will help.
Any ideas of what I can try?
