Nikon camera not found by gphoto

Gnome 2.28.2

Camera: Nikon Coolpix 5400, volume name NIKY2

Before I upgraded to FreeBSD 8.0 gphoto saw my camera and would import
photos. Now it does not.

Initial problem was that usb system would drop the connection. This
forum entry from http://forums.freebsd.org/showthread.php?t=7940 seems
to have fixed that problem:

Try creating file /usr/local/etc/hal/fdi/policy/preferences.fdi with
this content: Code: 
<?xml version="1.0" encoding="UTF-8"?>
<deviceinfo version="0.2">
 
  <device>
    <match key="volume.fstype" string="vfat">
      <match key="volume.size" compare_ge="128000000000">
        <merge key="volume.policy.mount_option.large" type="bool">true</merge>
      </match>
    </match>
  </device>

</deviceinfo>


Now the usb system mounts the camera but gphoto fails to recognize.
Error in GUI dialog is "An error occurred in the io-library ('Bad
parameters'): No error description available

At this point mount command includes:

/dev/msdosfs/NIKY2 on /media/NIKY2 (msdosfs, local, nosuid)

After some googling I found that others had solved a similar problem by
changing the camera from "mass storage" to "PTP." With that gphoto GUI
fails to open at all.

I noticed that /usr/local/share/doc/libgphoto2/camlibs lists many camera
makes, but not Nikon. In README.ptp2 I find my camera listed in a table,
along with a lot of other Nikons:

Model |Vendor ID|Product ID|
...
Nikon Coolpix 5400 | 0x04b0  |  0x0119  |

That readme suggests debugging with gphoto2. I had to install the port. 

gphoto2 -L gives

*** Error ***              
Could not detect any camera
*** Error (-105: 'Unknown model') ***  

In the debug output I see gphoto2 looking through all those camer files,
nothing for Nikon. Not necessarily a bug.

Note the vendor and product codes match.

I have installed the NTFS-3G port, if that matters.
