Thanks for pointing that out:

I cloned the git repos yesterday:
  git clone git://git.debian.org/sane/sane-backends.git
and did a default build.

Now I am able to scan:
  $ scanimage -L
  device `pixma:MX520_F934C5000000' is a CANON Canon PIXMA MX520
Series multi-function peripheral
  device `pixma:04A91769_12999B' is a CANON Canon PIXMA MX520 Series
multi-function peripheral
  $ scanimage>/tmp/img
  $

It also works without the usb cable connected:
  $ scanimage -L
  device `pixma:MX520_F934C5000000' is a CANON Canon PIXMA MX520
Series multi-function peripheral
  $ scanimage>/tmp/img
  $

Another problem with scangearmp is that it only does simplex ADF scanning.

I see similar behaviour:

 $ scanadf -v --source 'Automatic Document Feeder'

I haven't had the time to look further into this issue yet.
