Thank you William, that's interesting. The directory in jaunty is 
/etc/udev/rules.d, and there was no libsane.rules file there. However 
during the day I found somewhere a note that one is required and I added 
one named '70-libsane.rules' with the following contents, modelled on 
the 80-canon_mfp.rules file (which did exist) referred to below:

~~~~~~~~~~~~~~~~~~~~~~~~

# Canon PIXMA MP630
SYSFS{idVendor}=="04a9", SYSFS{idProduct}=="172e", mode="666", 
GROUP="scanner"

~~~~~~~~~~~~~~~~~~~~~~~~

This is the existing '80-canon_mfp.rules' file contents:

~~~~~~~~~~~~~~~~~~~~~~~~

# 80-canon_mfp.rules
ACTION!="add", GOTO="canon_mfp_end"
SUBSYSTEM=="usb_device", GOTO="canon_mfp_start"
SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", GOTO="canon_mfp_start"
GOTO="canon_mfp_end"
LABEL="canon_mfp_start"
# Canon MP160
SYSFS{idVendor}=="04a9", SYSFS{idProduct}=="1714", MODE="666"
# Canon MP510
SYSFS{idVendor}=="04a9", SYSFS{idProduct}=="1717", MODE="666"
# Canon MP600
SYSFS{idVendor}=="04a9", SYSFS{idProduct}=="1718", MODE="666"
# Canon MP140 series
SYSFS{idVendor}=="04a9", SYSFS{idProduct}=="172b", MODE="666"
# Canon MP210 series
SYSFS{idVendor}=="04a9", SYSFS{idProduct}=="1721", MODE="666"
# Canon MP520 series
SYSFS{idVendor}=="04a9", SYSFS{idProduct}=="1724", MODE="666"
# Canon MP610 series
SYSFS{idVendor}=="04a9", SYSFS{idProduct}=="1725", MODE="666"
#MP190 series
SYSFS{idVendor}=="04a9", SYSFS{idProduct}=="1734", MODE="666"
#MP240 series
SYSFS{idVendor}=="04a9", SYSFS{idProduct}=="1732", MODE="666"
#MP540 series
SYSFS{idVendor}=="04a9", SYSFS{idProduct}=="1730", MODE="666"
#MP630 series
SYSFS{idVendor}=="04a9", SYSFS{idProduct}=="172e", MODE="666"
LABEL="canon_mfp_end"

~~~~~~~~~~~~~~~~~~~~~~


So following your email, I've left the SYSFS characters in my 
'70-libsane.rules' file but added

ENV{libsane_matched}="yes" to the end of the line, disconnected and reconnected the usb cable, and tried xsane again. No difference.

lsusb gives the following:

Bus 001 Device 004: ID 04a9:172e Canon, Inc. 
Bus 001 Device 002: ID 046d:0990 Logitech, Inc. QuickCam Pro 9000
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
