Identifying an active USB device?

Whenever I use the 'Safely Remove Hardware' tool, I also see this mystery entry, with no drive letter.





(That had four entries, and I've just removed the USB with drive letter F: The remaining two K and E, are external WD hard drives.)

How can I discover what the unspecified USB device is please? And why does it have no drive letter?

what drives show up in device manager?

in disk management??

in device manager, go to view tab, click on show hidden devices, and see if it is listed there;, it might be an old drive that still loads the driver.

 

reply no. 2:

above from here

 

Thanks Elizabeth. I'll take a look at that registry tip later. Meanwhile (via googling extensively) I found a handy tool called USBDeview (my link is disallowed) and will use that first on the next occurrence of the puzzle.
