Thanks. The backend version will be listed in Synaptic as libsane - most
likely you are using 1.0.18-3ubuntu1.

You could always try the actual sane backend for your scanner:

Be sure to read & follow the instructions in:
easier to read:

Vendor CANON - ID: 0x04A9
USB Model:         ASIC:  Properties:              Prod-ID
CanoScan LIDE20    LM9833  600x1200dpi 48bit 512Kb 0x220D

Make sure to put your scanner ID info in /etc/sane.d/plustek.conf:

       [1]     [2]
[usb] 0x04A9 0x220D
device /dev/usbscanner

[1]=vendor ID
[2]=product ID

**Note** you might try the above in the plustek.conf before installing
plustek-usb-0.51-14.tar.gz just to see if that works. If it does then
fine, if not then install plustek-usb-0.51-14.tar.gz and see if that
works. Also see:

Also: make sure that you have your username in the scanners group:
System|Administration|Users and Groups|Manage Groups|scanner

And see if that works.
