Thank you for your fast response. I had checked memory initially and it was showing about 70% available. Believe it or not, I have repeated my steps of yesterday and I am not able to duplicate the problem. Not one thing has changed but I am now able to connect, stay connected, and can select "Device" in Calibre without any disconnects. Although this is good news,
something made the two misbehave and it would be nice to find out why so that others can avoid the experience.
I am scratching my head...
