title: Web app and USB communication without using NPAPI plugin
body: <p>I have NPAPI browser plugin for Chrome,Firefox  for a USB device. This plugin allows silver light web application to communicate with the USB device.</p>
  
  <p>Interaction involve<br>
  1.data transfer<br>
  2.querying USB device for info<br>
  3. and saving data in to USB device.<br>
  Recently <a href="http://blog.chromium.org/2013/09/saying-goodbye-to-our-old-friend-npapi.html" rel="nofollow">Chrome</a> announced that it  is not gonna support the NPAPI plugin in future.</p>
  
  <p>I have found PPAPI support will be there in chrome but it is not a standard and it will not work on firefox and other browser.Is there other way to achieve without using plugin.
  Do we have any other solution for this issue?</p>
