[sane-devel] Visioneer OneTouch 7100 USB

[m. allan noah]

#1 is odd, do you have a video capture card or camera?

#2 is because Xsane is only loading libraries in /usr/lib. There are
two fixes for this- rebuild sane 1.0.21 to overwrite the existing copy
(removing /etc/sane.d first)
or, modify /etc/ld.so.conf (or related files) to place /usr/local/lib
before /usr/lib.
