Comment 22 for bug 330383

Effell suggested fix works. I remove from /usr/share/hal/fdi/preprobe/10osvendor/20-libgphoto2.fdi
the portion where my player is nominated :

<match key="usb.vendor_id" int="1356">
    <match key="usb.product_id" int="806">
     <merge key="info.category" type="string">portable_audio_player</merge>
     <append key="info.capabilities" type="strlist">portable_audio_player</append>
     <merge key="portable_audio_player.access_method" type="string">user</merge>
     <merge key="portable_audio_player.type" type="string">mtp</merge>
     <append key="portable_audio_player.output_formats" type="strlist">audio/mpeg</append>
     <merge key="camera.libgphoto2.name" type="string">Sony Walkman NWZ-S516</merge>
     <merge key="camera.libgphoto2.support" type="bool">true</merge>
    </match>
   </match>

and now my "Sony Walkman NWZ-S516" when inserted is mounted in /media/WALKMAN
and it's fully browsable.
