removing part of a debian package that's interfering with my program

[Nigel Haslam]

Hi,

I have a RaspberryPi ZeroW running the latest Rasbian

PRETTY_NAME="Raspbian GNU/Linux 9 (stretch)"
NAME="Raspbian GNU/Linux"
VERSION_ID="9"
VERSION="9 (stretch)"

I'm trying to get a time lapse script package working, which works fine on
a RaspberryPi B+ but on the Zero I get an error:

Connecting
open_camera_dev_usb:usb_ptp_device_reset(): Device or resource busy
usb_ptp_get_device_status(): Device or resource busy
open_camera_dev_usb: ptp_opensession failed 0x2ff

Looking further into the USB device where my camera is connected I find:

root at raspberrypi_Zero-01:~/multilapse-CHDK/current# lsusb
Bus 001 Device 005: ID 04a9:32aa Canon, Inc.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

root at raspberrypi_Zero-01:~/multilapse-CHDK/current# fuser
/dev/bus/usb/001/005
/dev/bus/usb/001/005:   999

root at raspberrypi_Zero-01:~/multilapse-CHDK/current# ps ax |grep 999
  999 ?        Sl     0:00 /usr/lib/gvfs/gvfsd-gphoto2 --spawner :1.4
/org/gtk/g                                    vfs/exec_spaw/4
 1014 pts/0    S+     0:00 grep 999

So it seems that the process which is using the USB is
/usr/lib/gvfs/gvfsd-gphoto2

I had a similar issue with gphoto2 when I originally set up my RaspberryPi
B+, which I resolved by simply uninstalling gphoto2.  However, for some
reason, gphoto2 wasn't included in the slightly more recent distribution
that I installed on the PiZero, so I can't uninstall it.

Could you please advise how I might get around this issue?

Thanks in advance for your consideration

Nigel
