I stopped relying on USB connectivity entirely years ago, the hassle of working around driver issues with different operating systems along with different versions of operating systems, plus always needing to have a USB cable on hand everywhere I went was just too much. Now I just rely on WiFi, I like AirDroid but there are other viable options available in the Play Store. There is the caveat where your mobile device does need to be on the same local network as your target computer but it works on any consumer platform (Linux, Mac, Windows, etc.) and there are only two things necessary -- the AirDroid app on your mobile device and a web browser on the computer. (...and it makes no difference which one, Firefox, Chrome, Opera, IE, Edge, Safari, etc.)
