The answer was staring me in the face I forgot I had a USB port on a multiple card reader on the front of my Computer as I have never really used it. I only use one slot on this reader for my cameras memory stick. I took a USB flash drive device plugged it into the USB port on this Multiple reader and the problem resolved itself. I no longer have an Unknown USB device and it no longer matters if if I have a USB device plugged in or not.
I want to thank everyone for their help in resolving the problem
