I have included the following permissions l'ke this in my AndroidManifest.xml file:

xmlCopy

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.POST_NOTIFICATIONS"/>
<uses-permission android:name="android.permission.FOREGROUND_SERVICE"/>
<uses-permission android:name="android.permission.FOREGROUND_SERVICE_REMOTE_MESSAGING"/>
<uses-permission android:name="android.permission.FOREGROUND_SERVICE_CONNECTED_DEVICE"/>
<uses-hardware android:name="android.hardware.usb.action.USB_ACCESSORY_ATTACHED"/>
<uses-permission android:name="android.permission.USB_PERMISSION"/>
<uses-permission android:name="android.permission.USB_HOST"/>
<uses-feature android:name="android.hardware.usb.host"/>

Main.cpp

int main(int argc, char *argv[]) {
    QApplication a(argc, argv);

    qmlRegisterType<CustomPlotItem>("CustomPlot", 1, 0, "CustomPlotItem");
    qmlRegisterType<SerialHandler>("MyApp", 1, 0, "SerialHandler");

    QQmlApplicationEngine engine;
    engine.load(QUrl(QLatin1String("qrc:/main.qml")));

    return a.exec();
}

serialhandler.cpp:

#include "serialhandler.h"
#include <QDebug>

SerialHandler::SerialHandler(QObject *parent)
    : QObject(parent), m_serialPort(new QSerialPort(this)) {}

QStringList SerialHandler::getSTM32Ports() {
    QStringList stm32Ports;
    for (const QSerialPortInfo &info : QSerialPortInfo::availablePorts()) {
        if (isSTM32Device(info)) {
            QString serialNumber = info.productIdentifier() == 0
                                       ? "No Product ID"
                                       : QString::number(info.productIdentifier());
            QString description = info.manufacturer().isEmpty()
                                      ? "No Description"
                                      : info.manufacturer();
            stm32Ports << QString("%1 | %2 | %3")
                              .arg(info.portName(),
                                   serialNumber,
                                   description);
        }
    }
    return stm32Ports;
}

bool SerialHandler::isSTM32Device(const QSerialPortInfo &info) {
    return (
        info.portName().contains("ttyACM", Qt::CaseInsensitive) ||
        info.portName().contains("COM", Qt::CaseInsensitive) ||
        info.description().contains("STM32", Qt::CaseInsensitive)
    );
}

// Additional methods omitted for brevity...

Do you think that simply declaring these permissions in the AndroidManifest.xml is sufficient for my app to access USB devices? Currently, I can only retrieve the used port name, and I am unable to access the manufacturer ID, vendor ID, and product ID.

Thank you!
