Windows 10 won't eject USB thumb drive
I'm struggling with a peculiar little problem. My old faithful windows 10 computer will never eject the USB thumb drive. It doesn't ever show any errors. Its quite puzzling. I have several usb devices currently working including a 4TB usb hard drive, usb keyboard and mouse and a Fujitsu USB scanner. When I plug in the usb thumb drive, Windows makes the familiar boing noise and I can view the contents of the drive, but when I click the bottom right icon to eject, all goes well but explorer still sees the drive. I can manually remove the thumb drive from the usb port and Windows remains silent.
Looking in explorer, the device still appears and I am able to browse the I: (in this case) as if the thumb drive is still plugged in. I wonder why Windows thinks the drive is still plugged in. No errors appear in the error log. If I look in computer management/Disk Management, that just hangs. It just reports: "Loading disk configuration information."
Also if I look in Device Manager, under disk drives, there is a device there: OCZ ATV USB Device. (That is the thumb drive in question.)
When I try to reboot, the system just hangs and requires a hard reset (or pulling out the power cord.)
Do folks think this is a hardware or software issue?
I tried uninstalling the device from device manager but it never seems to actually work - just a green progress bar back and forth across the screen forever.

I do notice this in my error log:
The machine-default permission settings do not grant Local Activation permission for the COM Server application with CLSID
Wondering if it's related.
