I am setting up an old Ultra 1 as a scanner machine, and I have had some problems making sane connect to the SCSI-scanner. I have tried two different kernels, 2.2.20 and 2.4.17, both compiled with make-kpkg. It works only with the older kernel.
Below a copy of issued commands is seen. The machine has been rebooted but except from the differences in kernel versions, the two systems are identical. It is seen that the scanner (and the disk) are identified correctly in both cases, but for some reason "sane-find-scanner" fails under 2.4.17. The sg module is loaded in both cases. This looks like a bug in either the SCSI part of 2.4.17 or a bug in sane. Things work with 2.2.20, which means my problems are solved. I just report this since it might be of interest. (Hopefully this is not well-known already.) I will be happy to provide more information if someone needs it. B.t.w. could someone tell me the reason why the installation kernel is compiled without hardware clock support? /Pontus Johannisson %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% rosalia:~# uname -a Linux rosalia 2.2.20 #2 Wed Nov 26 15:47:00 CET 2003 sparc64 unknown rosalia:~# cat /proc/scsi/scsi Attached devices: Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: IBM Model: DORS32160SUN2.1G Rev: WA7A Type: Direct-Access ANSI SCSI revision: 02 Host: scsi0 Channel: 00 Id: 02 Lun: 00 Vendor: EPSON Model: Perfection1200 Rev: 1.03 Type: Processor ANSI SCSI revision: 02 rosalia:~# sane-find-scanner # Note that sane-find-scanner will find any scanner that is connected # to a SCSI bus and some scanners that are connected to the Universal # Serial Bus (USB) depending on your OS.
