Question

请查看以下代码

#include "MyClass.h"
#include <qstring.h>
#include <qdebug.h>

   MyClass::MyClass()
   {
       QList<QextPortInfo> ports = QextSerialEnumerator::getPorts();

       int counter=0;

       while(counter<ports.size())
       {
       QString portName = ports[counter].portName;
       QString productId= ports[counter].productID;
       QString physicalName = ports[counter].physName;
       QString vendorId = ports[counter].vendorID;
       QString friendName = ports[counter].friendName;


       string convertedPortName = portName.toLocal8Bit().constData();
       string convertedProductId = productId.toLocal8Bit().constData();
       string convertedPhysicalName = physicalName.toLocal8Bit().constData();
       string convertedVendorId = vendorId.toLocal8Bit().constData();
       string convertedFriendName = friendName.toLocal8Bit().constData();

       cout << "Port Name: " << convertedPortName << endl;
       cout << "Product ID:" << convertedProductId << endl;
       cout << "Physical Name: " << convertedPhysicalName << endl;
       cout << "Vendor Id: " << convertedVendorId << endl;
       cout << "Friend Name: " << convertedFriendName << endl;
       cout << endl;
       counter++;

       }
   }

我已连接“Dreamcheeky Thunder Missile Launcher”USB玩具，但我无法获得它的供应商ID或产品ID或至少与之相关的任何内容！见下图
