Detection usb device connection/disconnection

[QbelcorT]

Hi,
I made a response to this awhile back, see this thread. http://www.qtcentre.org/forum/f-qt-p...ent-18311.html
I am using QtEmbedded Linux. I got the USB device info (vendor id, etc) from the /proc/scsi/usb-storage file. I use a thread to monitor the existence of that file, amongst other things. Here is just a snippet of parsing that file, just for the vendor name so I can display it on a QLabel

responseConnection->hide();
QFile fileInfo;
QString usbInfoRaw, usbInfo;
QDir usbInfoDir(USBINFODIR);
if(!usbInfoDir.entryList(QDir::Files).isEmpty())
{
    qDebug() << usbInfoDir;
    fileInfo.setFileName(USBINFODIR + usbInfoDir.entryList(QDir::Files).first());
    if(!fileInfo.open(QIODevice::ReadOnly | QIODevice::Text))
      qWarning() << "Can't Get File" << fileInfo.fileName();
    QTextStream in(&fileInfo);
    QTextStream out(&usbInfoRaw);
    out <<  in.read(100) << endl;  
    usbInfo = usbInfoRaw.section(':',1,3);
    usbInfo.remove("Vendor:",Qt::CaseInsensitive);
    usbInfo.remove("Product:",Qt::CaseInsensitive);
    usbInfo.remove("usb-storage",Qt::CaseInsensitive);
    usbInfo.remove("Serial Number",Qt::CaseInsensitive);
    usbInfo = usbInfo.simplified();
   usbInfo.append(" ");
}
else
   qWarning() << "No File in Usb-storage";
 usbInfo.append(textDetect);
 uiResponseWin->label->setText(usbInfo);
 responseWindow->show();

responseConnection->hide();
QFile fileInfo;
QString usbInfoRaw, usbInfo;
QDir usbInfoDir(USBINFODIR);
if(!usbInfoDir.entryList(QDir::Files).isEmpty())
{
    qDebug() << usbInfoDir;
    fileInfo.setFileName(USBINFODIR + usbInfoDir.entryList(QDir::Files).first());
    if(!fileInfo.open(QIODevice::ReadOnly | QIODevice::Text))
      qWarning() << "Can't Get File" << fileInfo.fileName();
    QTextStream in(&fileInfo);
    QTextStream out(&usbInfoRaw);
    out <<  in.read(100) << endl;  
    usbInfo = usbInfoRaw.section(':',1,3);
    usbInfo.remove("Vendor:",Qt::CaseInsensitive);
    usbInfo.remove("Product:",Qt::CaseInsensitive);
    usbInfo.remove("usb-storage",Qt::CaseInsensitive);
    usbInfo.remove("Serial Number",Qt::CaseInsensitive);
    usbInfo = usbInfo.simplified();
   usbInfo.append(" ");
}
else
   qWarning() << "No File in Usb-storage";
 usbInfo.append(textDetect);
 uiResponseWin->label->setText(usbInfo);
 responseWindow->show();
