Hi, there is a different, when I scan the same image under windows with the origin software and iunder linux with sane. Under linux the picture is too dark and it seem that the dark parts are not detected by sane.
Is this a known problem ? I've made a histogramm of both images, which can be shown here: http://www.bloms.de/downloads/hist_lin.png http://www.bloms.de/downloads/hist_win.png Both picture are made with a gamacorrection of 2.20 and 150dpi 16bit If someone is interessested by the origin pictures, I will send you a private mail with a link to them. --snip-- bld@notebook:~> scanimage --version scanimage (sane-backends) 1.0.17; backend version 1.0.17 bld@notebook:~> --snip-- -- Gru?

The OS detects it fine (shows up as ugen), as does sane-find-scanner, and 'scanimage -L' seems to find it but gets a "could not read version register" error (see end). This problem occurs with backends 1.0.17 from FreeBSD ports and with sane-backends-2006-03-09.tar.gz (built by hand after removing the port installation). libusb is also from ports, v0.1.10a. I ran this as root, so there should be no device-access problems. A search for this problem in the list archives didn't appear to yield any relevant results. Thanks for any help.
