Windows 10: PC doesn't recognize usb flash drive

PC doesn't recognize usb flash drive

:)

 

OS doesn't recognize USB flash drives (KB4056892)

Just completed Win10 update KB4056892 on my Sony laptop, now running v.1709, build 16299.125. Almost everything is fine except the system no longer recognizes USB flash drives. When a flash drive (USB2 or 3) is inserted in a port the Device Manager recognizes it as "Other Devices", lists what it is (for example "TOSHIBA TransMemory USB Device") but says under Properties: "The drivers for this device are not installed. (Code 28) There are no compatible drivers for this device." When I try to update the driver, the Update Drivers feature says "Windows could not find drivers for your device." Device Manager shows no problems under Universal Serial Bus Controllers.

I know the drivers for flash drives are somewhere in the system because I have used these ports and flash drives many times prior to KB4056892, but I don't know where they are or how to tell the OS where they are. Suggestions would be appreciated.

Recovery Drive for Windows 10 Doesn't Recognize USB Drive

When I try to create a Recovery Drive in Windows 10, Windows doesn't recognize the flash drive.

I'm following the instructions to create a Recovery Drive listed here:

http://windows.microsoft.com/en-us/windows-10/create-a-recovery-drive

• 
  From the taskbar, search for Create a recovery drive and then select it. You might be asked to enter an admin password or confirm your choice. (I was asked to confirm my choice, and I clicked "Yes".)
  
• 
  When the tool opens, make sure Back up system files to the recovery drive is selected and then select
  Next.
  
• 
  (Secret Step) Wait a minute or so for the "Please Wait" screen to finish thinking
  
• 
  Connect a USB drive to your PC, select it ...
  

The issue is that when I connect a USB drive to the PC, it doesn't appear on the "Connect a USB flash drive" screen as a drive that can be selected, and the "Next" button is grayed out.

However, when I look in File Explorer, I can see the USB drive plugged into the computer. Selecting Properties shows that Windows considers its Type to be "Removable Disk". (Sounds right to me.)

I'm not getting any error messages.

My environment:

A brand new Toshiba Sattelite C55-C5241 laptop with Windows 10 Home. It's never had anything other than Windows 10 on it - unless they upgraded it at the factory.

A brand new ativa 8GB USB flash drive. Note that the packaging for the USB drive does not include Windows 10 in the System Requirements, but seriously?

What I've tried:

• Plugging the flash drive into all three USB ports (USB 2, USB 2, and USB 3)
• Reformatting the flash drive with FAT32
• Restarting the computer with the flash drive plugged in
• Turning off Real-Time Scanning in McAffee

I've seen a few threads with this issue in Windows 8, but none of the potential solutions in those threads have worked for me. So here I am asking the same question, but for Windows 10.

Does anyone have any suggestions for resolving this issue?

Thank you.
