Well, the kernel scanner driver does detect the scanner. So from the kernel's point of view, it is supported. > also no SANE support. There is also a SANE backend (niash), it's just not included in the standard SANE distribution (yet). > Through the SANE Home Page links now I know that I need the "SANE backends > for > flatbed scanners with the NIASH chipset" for to work with my scanner.

The reason for this is that installing sane-backends twice at different locations may cause trouble. You can do that, but the following problem will occur: scanimage will work, if you use the version from /usr/local/bin. But xsane/xscanimage or any other frontend from your distribution will use the old sane-backends and so won't find your scanner. > But if I want to remove my SANE packet (is the sane-backends-1.0.9-3.1mdk and > sane-frontends-1.0.9-1.1mdk) I need to remove also this software: > > libsane1-1.0.9-3.1mdk > libsane-devel-1.0.9-3.1mdk > xsane-0.90-1.1mdk > xsane-gimp-0.90-1.1mdk Sounds somewhat sane :-). You could just remove libsane* and ignore the dependencies. Your packet manager will most likely annoy you every time you install software later, however. > And the dependencies that suppose remove also: > > kdegraphics-3.0.3-11mdk > kdegraphics-devel-3.0.3-11mdk > kdevelop-2.1.3-6mdk > koffice-1.2-3mdk > koffice-devel-1.2-3mdk > koffice-i18n-es-1.2-1mdk Well, if I made packages like koffice or kde*, I wouldn't do that :-) Ask your distributor if they have sane-backends packages including the niash backend or at least a package containing only the niash backend. If they don't provide such packages, you could try to make one yourself, if you have a little experience with RPM. Or try one of these tricks/hacks: - Overwrite the old sane-backends installation by specifying arguments to configure (e.g. --prefix=/usr --sysconfdir=/etc). Check where your distribution's files are. That's ugly and may cause trouble when removing the distribution's sane packages later or when upgrading. - Install your new sane-backends as usual and trick xsane into loading the libraries from /usr/local/lib. "LD_PRELOAD=/usr/local/lib/libsane.so xsane" may do the trick. - Create a dummy sane-backends RPM package that just claims to provide sane-backends. So you can install your own version. All these tricks are rather ugly hacks. If you want to stay with your package system, you'd better get RPMs. > I have a Mandrake 9.0 distro with 2.4.19 Kernel version with the USB module > charged at init (UHCI) and the sane-find-scanner returns that: > > # No SCSI scanners found.

Both the kernel scanner driver and libusb have found the scanner. Bye, Henning
