Summary: gphoto2 -L does not work

Initial Comment:
In response to request for information about behavior of Nikon P500, dmesg indicates the camera picked up by the USB driver. gphoto2 -L does not produce output that is easily seen and seems to hang.

Message:
This looks like gvfs-gphoto/libgphoto2 is having issues dealing with the
USB device. This is a lower level issue with USB.

Message:
rebooted to clean up the state of the machine
gvfs processes did not change when the camera was plugged in, nor did an
icon appear
the dmesg may give a hint, the USB mount appears to have been delegated to
a gphoto2 related process which failed

Message:
It is not reacting to any command we send in the trace.

is another process blocking the camera, like GNOME gvfs (nautilus camera
icon?)

Message:
Please see uploaded file. I notice among other things that no nikon library
seemed to be accessed. BTW without the logfile option a rather abbreviated
version appeared on the screen. With that option, I had to exit with ^C.
