Why won't Arduino connect to Raspberry pi?

Question

Arduino

Wrote a program to work with Arduino. From a desktop computer it works without problems, the computer communicates with the arduino and everything goes as it should. But if I try to connect the board to the raspberry pi, the port opens, but nothing can be transferred to the board or read from it. I immediately thought, maybe I wrote something crookedly, freaked out, installed the Arduino IDE on the raspberry and tried to experiment for the sake of uploading the sketch. As a result, the IDE sketch compiles and stupidly hangs at the moment when the board should start loading:


I tried to insert arduino into different USB ports - everywhere the same story. Power comes to the arduino, something like a sketch that is already loaded in it - it starts and works, but there is no data exchange from the word at all. What could be the reason for this behavior? Something I have no idea in which direction to start digging. I repeat that:

• The Arduino board itself is working, on a desktop PC everything works as it should
  
• On raspberries, usb ports are also working, if I insert a USB flash drive into them, it is read without problems.
  

Answer 1

Is the correct port selected?
You can do a loopback test
