So far the one my sister is using seems to be working, or she'd have mentioned that.

I am kicking myself now for not having looked harder before when I couldn't get my Amazon Fire tablet to talk to the computer. I have been thinking about getting a Samsung tablet just so I had one that would behave nicely and let me move files back and forth - but instead of buying that tablet I made myself make one more attempt.

It's a two-part answer. It doesn't want to connect with Bluetooth, and it wants to connect with a USB-3.1 cable and I had the cable on a much slower 2 or 1 port on the hub. AND on the tablet when you pull down from the top of the screen and see the message about the USB charging, you then (once it's plugged into the USB 3 port) can see the guts and the card in the tablet while in Windows Explorer. It only took an effing year of playing games with moving files via thumb drives. And of course, it took a flashlight and moving the computer table to get a look at the ports on the back and then to realize that I have two little class C USB 3.0 ports that I haven't been using because I don't have those cables. Now they're ordered. And this illustrates why the cataracts are such a pain - needing the flashlight to do any of this stuff. I made a point of getting lots of 3.1 ports when I ordered this, I just didn't pay attention that they fit a different cable. I have some adapters I can use, but dedicated cables are better. #FinallyGettingAroundToDoingTheMath

Jon, back to you. Your turn. :-)
