Thanks for the suggestions.
I did try switching to all the different USB ports on my PC. I tried the 4 on the back, the 2 on the top, and 2 on the front, and got the same results with each one.
I have rebooted the PC a number of times, with the safely removed before shut down and reboot. That did not help either.
I have not tried to remove and re-install the driver. I will try that later.
Thanks for the ideas.
