Latest Norton update blocks USB Drivers on Dell XPS 15 with latest WIndows 10
On the evening of Friday, February 16, 2018 something wiped out my USB and Touchscreen drivers on my Dell XPS 15 9560 4K UHD. Device Manager showed the drivers were missing, although a Dell driver scan showed that all of the drivers were there. Reinstalling the drivers didn't help, nor did any of the usual things like uninstalling the devices and rebooting to let Windows re-find them. But I knew the hardware was good, since it would pass diagnostic tests during POST and my USB mouse worked fine in the BIOS. After HOURS of testing, which included going back in time by recovering from previous image backups only to have the problem reoccur within a few hours, I traced it down to a combination of a recent update to Norton 360 (Comcast Xfinity version) and a recent Windows 10 update (KB4074588, I believe), both of which appeared to have occurred on Friday night, and both of which are needed for the problem to occur.
The only way that I was able to regain use of my USB ports or Touchscreen was by uninstalling Norton 360, uninstalling Windows 10 update KB40074588, and rebooting. I was then able to allow Windows Update to reinstall KB40074588 without the problem coming back. So now I'm unable to use Norton, at least until this problem gets corrected.
I'm not sure what the Norton update was that triggered this issue (can't check version since I've uninstalled it), but I believe that it was the 22.12 version update.
Has anyone else seen this problem? If so, can anyone verify that it has been corrected in Norton?
