Zdravím všechny. Jestli někdo zná PROCESSING programovací nástroj tak jsem sestavil prográmek na idetifikaci USB pod WINDOWS tak pod LINUXEM.
Tu je :

import processing.serial.*;
Serial port;
StringList usb = new StringList();
String OS[] = {"WINDOWS", "LINUX"};
String Chip_id[] = {"PL2303", "CH340G", "CP2102"};
byte Os, ID, Port;
int delka, delka_pom;
boolean ready = false;
String chyba, Idvendor, Usb, props;
boolean device_detected = false;
String Text ;
String[] port_list;
String[] Id;
String detected_port = "";
//*************************************
void setup() {
  ID =0;
  size(500, 60);
  fill(0);
  text("USB INFO:", 0, 10);
}
//*************************************
void draw() { // telo programu
  USB_informace();
  delay(500);
}
//*************************************
void mousePressed() { // UKONCENI PORGRAMU
  if (mouseButton == RIGHT) {
    exit();
  }
}
//**************************************
void USB_informace() {
  usb = new StringList();
  usb.append(Serial.list());
  background(200);
  text("USB INFO:", 0, 10);
  if (usb.hasValue("/dev/ttyS0")) {
    Os = 1;
  } else if (usb.hasValue("/COM")) {
    Os = 0;
  }
  //***************************************
  if (Os == 1) { // linux USB
    delka = usb.size();
    if (usb.size() > 1) {
      for (int i=0; i < usb.size(); i++) {
        //Map<String, String>
        props = (Serial.getProperties(usb.get(i))).toString();
        Idvendor = trim(props);
        Id = match(Idvendor, "idVendor=1a86");
        if (Id == null) {
          props = (Serial.getProperties(usb.get(i))).toString();
          Idvendor = trim(props);
          Id = match(Idvendor, "idVendor=067b");
          ID = 0;
        }
        if (Id == null) {
          props = (Serial.getProperties(usb.get(i))).toString();
          Idvendor = trim(props);
          Id = match(Idvendor, "idVendor=10c4");
          ID = 2;
        } else {
          ID = 1;
        }
        if (Id != null) {
          Usb = usb.get(i);
          Text=("OS: "+OS[Os]+" Port: "+Usb+" Chip com: "+ Chip_id[ID]);
          text(Text, 0, 21);
          break;
        } else {
          Text=("OS: "+ OS[Os]+ " Nezapojeno do USB.");
          text(Text, 0, 21);
        }
      }
      //PL2303 idProduct=2303 idVendor=067b
      //CH340g idProduct=7523 idVendor=1a86
      //CP2102 idProduct=ea60 idVendor=10c4
    }
  }
  //***************************************
  else if (Os == 0) { // Windows USB
    if (delka_pom == 0) {
      delka = Serial.list().length;
      delka_pom = delka;
    } else {
      delka = Serial.list().length;
      if (delka_pom == delka) {
        delka_pom = delka;
        device_detected = false;
      }
    }
    port_list = new String[delka];
    for (int i = 0; i < delka; i++) {
      port_list[i] = Serial.list()[i];
    }
    // see if Arduino or serial device was plugged in
    if ((Serial.list().length > delka_pom) && !device_detected) {
      device_detected = true;
      // determine which port the device was plugge into
      if (delka == 0) {
        detected_port = Serial.list()[0];
      } else {
        // go through the current port list
        for (int i = 0; i < Serial.list().length; i++) {
          // go through the saved port list
          for (byte j = 0; j < delka; j++) {
            if (Serial.list()[i].equals(port_list[j])) {
              Port =j;
              break;
            }
          }
        }
      }
    }
    if (Port == (delka - 1)) {// vypis COMu
      detected_port = Serial.list()[Port];
    }
    if (!device_detected) {
      Text=("OS: "+ OS[Os]+ " Nove nezapojeno do USB.");
      text(Text, 0, 21);
    } else {
      Text=("OS: "+ OS[Os]+ " Port: "+ detected_port);
      text(Text, 0, 21);
    }
  }
}

Tu je mustr na vložení do programu:

//****************** ostatni *********************
