good day guys
I have a project in which i have to connect to the internal chip of a mouse and perform some actions ​​such as applying changes on the RGB sensor and so on by using Java language. I’ve worked with serial ports with JSSC library before and I am familiar with this type of ports. My questions are :

1. How can I connect to the internal chip of the mouse using the serial port?

2. How are the algorithms of these types of ICs?

3. Is it possible to connect with the firmware of these types of mice using the serial port?

Any feedback would be appreciated

I use this class to connect to the devices by using serialport . When i plug the serialport of the mouse i cant connect to the chip . I checked different COM numbers but i got port busy from the active ones . I think thats because of using wrong input parameters .

import jssc.SerialPort;
import jssc.SerialPortEvent;
import jssc.SerialPortEventListener;
import jssc.SerialPortException;

public class serialreader {

    private static SerialPort serialPort;

    public static void main(String[] args) {

        serialPort = new SerialPort("COM Number");
        try {

            serialPort.openPort();

            serialPort.setParams(SerialPort.BAUDRATE_9600,
                                 SerialPort.DATABITS_8,
                                 SerialPort.STOPBITS_1,
                                 SerialPort.PARITY_NONE);

            serialPort.setFlowControlMode(SerialPort.FLOWCONTROL_RTSCTS_IN | 
                                          SerialPort.FLOWCONTROL_RTSCTS_OUT);

            serialPort.addEventListener(new PortReader(), SerialPort.MASK_RXCHAR);

            serialPort.writeString("Get data");
        }
        catch (SerialPortException ex) {
            System.out.println(ex);
        }
    }

    private static class PortReader implements SerialPortEventListener {

        @Override
        public void serialEvent(SerialPortEvent event) {
            if(event.isRXCHAR() && event.getEventValue() > 0){
                try {

                    String data = serialPort.readString(event.getEventValue());

                    serialPort.writeString("Get data");
                }
                catch (SerialPortException ex) {
                    System.out.println(ex);
                }
            }
        }
    }
}

What are correct params for this kind of chips ?
Is there any datasheet for this kind of chips ?
