I just had to pull mu desktop out of its hole. I found out that if I plug the thumb drive into a USB port of the back of the computer it is recognized.
I did not find the Realtek driver listed when I tried the method above. (Download driver from Dell). I found the driver on the internet and downloaded it. The computer still does not recognize the thumb drive.
I recently upgraded to Windows 11. My computer will not now recognize a thumb drive inserted in a USB port. I have tested all of my USB ports by connecting to other devices (iPhone and pocket drive) with them. I am able to transfer from or to my iPhone and can read the files on my pocket drive...
