Thanks for the suggestion. Of note, I think it is not compatible with Windows 10. I only have a Win10 PC, with both USB 3.0 and USB 2.0. It doesn't even register my phone on USB 3.0; with USB 2.0, my PC detects my phone, but the software updater program does not.
I'm going to try it on my wife's Mac and see if I can get it to work.
