What model scanner? Oh, you said: Microtek E6 (sorry!). Please attach the output of 'sane-find-scanner -v' and 'scanimage -L'. Thanks. [root@bennew01 endur]# /usr/bin/sane-find-scanner # Note that sane-find-scanner will find any scanner that is connected # to a SCSI bus. It will even find scanners that are not supported # at all by SANE.

[microtek] sane_exit: MICROTEK says goodbye. [root@bennew01 endur]# Yes, if I use 'scanimage -d microtek:/dev/sg5', this works :-) The scanner starts up to scan. Of course, the microtek.conf file is in /etc/sane.d/microtek.conf. If there I change the path to /dev/sg5 - this works too. So this is solved, but in sane 1.03, I have not to change microtek.conf. The problem seems to be with the device matching in /proc/scsi/scsi. What does 'cat /proc/scsi/scsi' say? # cat /proc/scsi/scsi Attached devices: Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: IBM Model: DPSS-318350N Rev: S80D Type: Direct-Access ANSI SCSI revision: 03 Host: scsi0 Channel: 00 Id: 01 Lun: 00 Vendor: IBM Model: DPSS-318350N Rev: S80D Type: Direct-Access ANSI SCSI revision: 03 Host: scsi0 Channel: 00 Id: 02 Lun: 00 Vendor: NEC Model: CD-ROM DRIVE:466 Rev: 1.26 Type: CD-ROM ANSI SCSI revision: 02 Host: scsi0 Channel: 00 Id: 03 Lun: 00 Vendor: TEAC Model: CD-R58S Rev: 1.0M Type: CD-ROM ANSI SCSI revision: 02 Host: scsi0 Channel: 00 Id: 04 Lun: 00 Vendor: iomega Model: jaz 2GB Rev: E.17 Type: Direct-Access ANSI SCSI revision: 02 Host: scsi1 Channel: 00 Id: 06 Lun: 00 Vendor: Model: Scanner 600 Rev: 1.90 Type: Scanner ANSI SCSI revision: 03 There are two scsi-cards inside: 1. Adaptec 29160N (aic7xxxx statical linked in the kernel) for UW 160 HD's, 2. Dawicontrol (module tmscsim) for the scanner only. Always the same /dev/sg5, this doesn't change, I'm sure about this. ln -sf /dev/sg5 /dev/scanner solves the problem for me now. In result, I have not to change always the /ect/sane.d/microtek.conf. No probs so far. I think I can see the problem. The 'vendor' field that the SCSI device returns is blank, and that confuses the matching routine. Yes, yes, I think you have found the problem. The scanner is identified on the bus as an dumb 'Scanner 600' without vendor-information. This is well known for all Microteks E6. But the matching routine must have changed in sane 1.05, must be stricter now, not only simple matching the string 'scanner' as before. But this I *think* I'm not sure. Regards from Germany Matthias A fix for this problem is already committed to CVS, it seems (after 1.0.5 was released). When SANE 1.0.6 is released (quite soon now), it will include this fix. I'll let you know when I have a package built for it. This is in rawhide now (1.0.6-1). Thanks for your hint about the new packages in rawhide. An simple rpm-upgrade fails for me -> missing libgimp-1.2.so.0 -> newer one is always installed and missing libusb-01.so.4 -> don't know much about this, we don't using USB on this server. Because the machine is an important one, used as file-and print-server in our company, I could not doing more about this at this time. Regards from Germany Matthias On my Red Hat Linux 7.2 system libgimp-1.2.so.0 is provided by gimp-1.2.1-7, and libusb provides libusb-0.1.so.4 (SANE 1.0.6 supports some USB devices and does so via libusb). But you are right not to install Rawhide packages except in a test environment. I'm not tremulous, if I before the server, the Rawhide packages for sane, I
think, have no much effect about the stability. But for the sane 1.06 I have to
downgrade gimp from 1.2.2 to 1.2.1-7, and in result, I have to recompile xsane
0.80 too. ln -sf /dev/sg5 /dev/scanner solves (as stupid workaround) my problem
very simple.
regards from Germany
