I just installed this tool
https://forum.xda-developers.com/showthread.php?t=2588979 
and it fixed my problem.  I suspect it was because the tool installs the right driver.  I downloaded it from the "Google" URL on that page

To add more info - it only fixed things for my Google tablet.  Which identifies as Asus Nexus 7.  So far this method didnt help me connect to my LG Android phone.  Perhaps I should select a different drive from that web page.
