I have configured SANE built from MacPorts (sane-backends @1.0.22_0+universal) for the Visioneer OneTouch 7400 scanner, similarly to what's mentioned in [sane-devel] How to get Visioneer Onetouch 7400 working, F11 x86_64<http://lists.alioth.debian.org/pipermail/sane-devel/2009-August/025176.html>, but the result is somewhat strange: all color scans have a reddish hue, and various adjustments in xsane don't help. I have an example scan[1] (including the calibration area as discussed in debugging the GT68xx backend) and verbose (255) log[2], but don't really know what's going on in there. The same scanner works fine under Windows with the vendor driver (aside from the bundled software being a bit cr*p...). Suggestions?
