[sane-devel] sane-find-scanner works but scanimage does not find a scanner

[Jim Newton]

hi wolfgang, i was indeed able to get the scanner working yesterday.
although it no longer works today.  In the directory /usr/lib/sane
had contained lots of links to 1.0.5 files.  but the 1.0.5 files did
not exists,  since the 1.0.7 files did exist, i removed the invalid
symbolic links and replaced them with valid 1.0.7 links.   after that
the scanner worked.

the snapscan e40 does not have a power button.  the only way i can
turn it off, is to unplug it.  when i try to run xsane, xsane cannot
figure out if the scanner is warming up, or disconnected.  i suspect
that is the problem now... but i have no idea how to solve it.

what i saw was it worked until i went to bed last night.  but this
morning when i woke up i get the following errors from scanimage.

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).
