title: Install .wgt file on tizen TV with USB
body: <p>I have hard time installing .wgt file on TV with USB. App works normally on emulator. I have all required certificates. My distributor certificate has public privilege level with DUID of my emulator and my tv (where I want to test my app). In my USB root i created userwidget folder and copied .wgt file in it. When I plug USB in tv it detects it but after a few seconds I get message something like this: Installation with USB package is failed.
  I have tried almost everything and I am running out of ideas what could be wrong. I assume is something with certificates/permissions but don't know what. My tv model is UE48J5570.</p>
  
  <p>Updated:
  I have also developer mode enabled on tv and signed in as develop user.</p>
