Thank you. I did not have that installed. I did so, rebooted, and no success. I then tried the response of the post I mentioned but did so incorrectly, adding it to the modules file. There is not a usb3 file there. Perhaps, I should add one?
I didn’t realize that this machine has one of those type C ports in the front, and I just tried someone else’s fancy little drive and it was qucikly recognized and I could see the files in Dolphin. Only those ten 3.0 ports don’t recognize the flash drives.
