title: USB Barcode scanner opens browser's downloads page
body: <p>I'm trying to scan some barcode to textfield contained in my browser but it opens the downloads page in any browser (chrome, firefox, ie). 
  I'm guessing that there is some input equivalent to CTRL + J that triggers the browser to open the download page.</p>
  
  <p>Is anyone ran into this problem? Is there a way to pass it (assuming that I my clients can't change their scanner configuration neither the browser configuration)?</p>
  
  <p>Thanks.</p>
