  • 4duino USB port not found in device manager..

    Hi. I am using 4duino.
    Using a library called CustomSoftwareSerial in 4duino, I uploaded the code to 4duino with Arduino IDE,
    but after uploading, the port is not detected in device manager.
    How do I fix it so that the port can be caught? Please help me.
    (I use SoftwareSerial, but I had to set up Config, so I searched Google and used the CustomSoftSerial library)

    Below is the code I uploaded to 4duino.

    #include <CustomSoftwareSerial.h>
    CustomSoftwareSerial* customSerial; // Declare serial
    void setup() {
     while (!Serial) {
     Serial.write("Hello World");
     customSerial = new CustomSoftwareSerial(10, 11); // rx, tx
     customSerial->begin(115200, CSERIAL_8E1);
     customSerial->write("Test message"); // Write testing data
    void loop() {
    if (customSerial->available())
    if (Serial.available())

    Good day!

    Have you tried burning the 4Duino bootloader? Usually, this can fix the issue you are having with not detecting the port.

    I am not quite familiar with CustomSoftwareSerial. Can you tell me more details regarding why you need to use this? I am not particularly sure I understand what you previously stated.

      Hi. Good day!

      Now finding the 4duino port solved it.

      4duino tried to perform serial communication using SoftwareSerial,

      but parity setting to even is not supported.

      So, while looking for a way, CustomSoftwareSerial said it could set the parity and used it.

      Now I waited for the current port to pop up for a while

      and uploaded another code and I was able to find the port.

      Thanks for trying to help.
