Try

SANE_DEBUG_DLL=255 SANE_DEBUG_V4L=255 SANE_DEBUG_COOLSCAN=255 scanimage -d coolscan:/dev/scanner

to get some more information if coolscan is even used.

Maybe a problem with the shared libraries. It looks like libsane.so.1
points to (or is) libsane-v4l.so. Can you check this? Maybe you have
/usr/lib/sane in your ld.so.conf (don't do this for newer SANE
versions). Did you install sane in prefix /usr (instead of /usr/local)?
Then this /usr/lib/sane/libsane.so.1 is probably an old version.
Remove the old SANE files before installing the new libraries.

Bye,
Henning
