Ethernet via USB C?

I could not find any compatibility information except that it works on Windows:

  • Supported operating systems: Microsoft Windows 7 (32bit & 64bit), Windows 8 (32bit & 64bit), Windows 8.1 (32bit & 64bit), and Windows 10 (64-bit)

So maybe it doesn’t support Android. Can you try a class-compliant dongle with Android support?
