USB ports not working after update April 14, 2020—KB4549951

None of my usb ports or devices show up after the update April 14, 2020—KB4549951. I've verified this by rolling out the update - all devices and drives work - install it and none show up.

I've turned off updates for the time being but I'd like to fix this issue I can only stall the update off for so long and have NO idea how to fix this mess. 

Thanks for any help.

That doesn't seem to be the solution I need. It's directly related to the latest update. Update installed usb devices don't work. Roll it out and they work. I've tried everything I can think of and for now have just stopped the update.. but that will only last me for so long. Any other ideas?

Not seeing this on any of my 5 Windows 10 machines. Make sure your BIOS and all firmware and drivers are up to date.

In addition is this impacting all types of devices connecting to USB port or limited only to Storage devices? If limited to storage devices what kind of Storage devices are connected? Please be specific such as for example, 32GB Kingston Flash drive, Seagate External HDD USB3, UAS External Storage device <<Mention Model and Size>>>

Over the last two weeks, I'm having problems with my USB mice on both my Windows 10 machines -- but not with my other external USB devices.  If anyone knows when Microsoft will fix the problem they created, it would be very welcome info.

TIA.
