Please follow the following steps to know how to communicate or send data from ESP8266 or arduino to raspberry pi using USB serial communication
1)First please open your Arduino IDE
2)Now please upload the following code to to your ESP8266

void setup() 
{
Serial.begin(115200);
}
void loop()
{
delay(10000);
Serial.write(100);
Serial.write(-10);
Serial.write(-1);
}

3)Now please power your raspberry pi

4)Connect ESP8266 to the raspberry pi using USB which is shown below

5)Now please open the raspberry pi terminal and execute the following command to know the USB port

6)Now please download the following python code which will receive data serially from ESP8266 on the USB port number

7)Now please unzip downloaded code and open with python IDE in raspberry

8)Now please modify the serial port number in the code which we have found in step 5

9)Now please run the python script to receive data from ESP8266
