title: Android Marshmallow USB OTG issue
body: <p>I have a problem with the <em>OTG</em> function on <em>Marshmallow</em>.</p>
  
  <p>With <em>Lollipop</em> when I plugged my external storage , I could access the files on my <em>OTG</em> storage with the Storage Access Framework.
  Now when I plug it with <em>Marshmallow</em> I can't access my files with my apps as if my <em>OTG</em> storage was not mounted as before.<br/> 
  I used <em>ES Explorer</em> with <em>Lollipop</em> and my <em>OTG Storage</em> was mounted in <code>/storage/USBstorage1</code> but now it is recognize as <code>usb://</code> and I think it is why I can't access my file with my apps now.</p>
