HI,
After the gio mount -s gphoto2 , look
for still running processes with
ps auxw |grep gphoto
and kill the pids listed (gvfs-gphoto2-monitor or similar names).
After that
gphoto2 --summary
should not report blocked device anymore.
Then try
gphoto2 --capture-image
However, as I wrote earlier, remote capture might just not be supported over
USB.
Ciao, Marcs
