After Windows 8.1 Update USB3 Broken

I applied the latest round of Windows 8.1 updates last night and found myself unable to access my external Toshiba hard drive, which uses a USB3 port. Turns out that the update broke my USB3 drivers.

It doesn't appear that I'm the only one that has experienced this. I did however find a pretty easy fix for it. Simply go into Device Manager and you should see that the icon for the USB3 hub has a problem due to the "!" icon.

Uninstall the drivers for that hub and be sure to check the checkbox to delete the files from your computer. Then Scan for Hardware changes and it will automatically detect and reinstall the drivers  for that from the Internet.

Drivers are healthy again and now I can access the drive.

Good Luck!
