title: Weird URI string displayed on mounting iPod
body: <p>I have written a small program to detect whenever a device is mounted on a desktop running Linux. I have used <code>GIO</code> for this. I am extracting the URI of the mounted resource and displaying it to the user. When I put in a CD I get a URI string which looks like <code>file:///media/cdrom0/</code> which I can understand. But when I mount an iPod the URI I see is something like <code>gphoto2://[usb:002,028]</code>. What does this mean? I have observed that the second number (028) keeps increasing every time I take the device out and plug it back in. Can some one interpret this URI for me?    </p>
  
  <p>Update: As shodanex answered, the two numbers are the bus number and device number respectively. <code>gphoto2://</code> indicates the protocol (PTP/MTP).</p>
