What exactly does "blah, blah, blah" error message mean? WiFi is the recommended type of connection to use, which is why the USB connection option isn't even available by default without enabling additional settings. There are also instructions on how to connect over USB using the companion app under the help menu - did you go through those instructions? You have to install specialized drivers, and if someone hasn't set up the properties for your particular device with the Universal ADB drivers, then you'd have to figure out the correct values and modify the configuration for the drivers yourself. It's incredibly tedious to connect over USB, because Google considers it a security risk and won't allow raw data to be sent over USB. So the only way to send data over USB is to use developer tools to get around these limitations, which requires enabling things like USB debugging in the device settings.
