title: Motorola MC3190 barcode scanner not getting triggered
body: <p>I am trying to get my Motorola MC3190 read barcode. But unfortunately there is no response after pressing the hardware scan button. I am using EMDK for .net version 2.0. </p>
  
  <p>Here is my code:</p>
  
  <pre><code>private void Form1_Load(object sender, EventArgs e)
          {
              // Get the first scanning device (Its named SCN1 in my device) 
              myDevice = Symbol.Barcode.Device.AvailableDevices[0];
              myReader = new Reader(myDevice);
  
              // Make sure the Code-128 decoder is enabled!
              myReader.Decoders.CODE128.Enabled = true;
  
              // Create an instance of reader
              myReaderData = new Symbol.Barcode.ReaderData(Symbol.Barcode.ReaderDataTypes.Text, Symbol.Barcode.ReaderDataLengths.MaximumLabel);
  
              // Set the event handler
              myReader.ReadNotify += new EventHandler(myReader_ReadNotify);
  
              // enable and get ready to read
              myReader.Actions.Enable();
              myReader.Actions.Read(myReaderData);
          }
  </code></pre>
  
  <p>In my event, I am simply trying to get the decoded text displayed:</p>
  
  <pre><code>void myReader_ReadNotify(object sender, EventArgs e)
          {
              Symbol.Barcode.ReaderData nextReaderData = myReader.GetNextReaderData();
              this.listBox1.Items.Add(nextReaderData.Text);            
              switch (nextReaderData.Result)
              {
                  case Symbol.Results.SUCCESS:
                      this.listBox1.Items.Add(nextReaderData.Text);
                      myReader.Actions.Read(myReaderData);
                      break;
  
                  case Symbol.Results.CANCELED:
                      this.listBox1.Items.Add("Canceled!!");
                      break;
  
                  default:
                      string sMsg = "Read Failed\n"
                      + "Result = "
                      + ((int)nextReaderData.Result).ToString("X8");
                      MessageBox.Show(sMsg, "ReadNotify");
                      break;
              }
  
  
          }
  </code></pre>
  
  <p>I do <strong>not</strong> get any error messages. At the same time, if I list my available scan devices, I am able to see my device namely (SCN1). Is there anything special I need to do to trigger the hardware key? </p>
  
  <p>Any help / ideas to resolving this issue is highly appreciated. Thanks!</p>
