USB 2.0 not working, but system restore fixes it

For my edification, please help identify why this happened.
The PC is an HP, using Win 7, 8Gb RAM, all Windows updates current. Norton AV up to date.
Today, I couldn't get a single USB 2.0 slot to work. Card reader, too. I have a PCI slot for a USB 3.0. That did work.
When I checked the Device manager for the USB connections, several of them said that Windows could not load the drivers. I checked for updating the driver software, but it said it was up-to-date.
I did a system restore point, roughly a week ago, and now those 2.0 ports are working again.
What would cause this to happen? Thanks.
