Start by finding out which device file you really need. This can be done by observing which file appears/disappears as you connect/disconnect the Arduino, or by inspecting kernel messages with dmesg immediately after the Arduino was connected. Lines you have posted are not error messages. Go to File-> Preferences in Arduino IDE and check the corresponding ...

Arduino Uno uses a separate chip for USB to UART interface. As a result it will always look like a UART (/dev/ttyUSBx or /dev/ttyACMx) on the Pi, and the only way to exchange information will be to open the UART (with the right baudrate!) and send data to the Arduino, which then can reply and tell what's connected to it. Arduino Leonardo / Due controllers ...

You could use an UART, either via a 3-wire cable (TX, RX and GND) or wireless via modules such as HC-11 (though that is added hardware). You could use an Enthernet cable for that: one twisted pair carries TX/RX, and the rest of the wires carry GND.
