title: Handling of device insertion and removal on Embedded Linux
body: <p>I have an application for the USB interface in QT (Embedded linux).</p>
  
  <p>When Pendrive inserted kernel sends a signal for that and i want to recognize that signal and want my QT application to detect it.</p>
  
  <p>I went through the unix signal handling tutorial of QT but i could not find any way of my problem.</p>
  
  <p>I implemented the same thing as done in the tutorial but i did not find the way to detect the pendrive. It only kills the processes.</p>
  
  <p>Please go through the following link.</p>

  <p>I have also found using QdBus library of qt. I cross compiled it but gave me the errors of lidbus version.</p>
  
  <p>Is there any other way to detect the external pendrive from the application ?</p>
