Hello sane/xsane developers and users,
At first I want to say a big "Thank you!" to all the people who are developing these great pieces of software. I'm using them since a very long time locally on my desktop and I also give some people the possibility to use my scanner(s) over the network via saned. It works perfectly without any trouble and problems. This is, what I understand under "Plug (& very little config work) & Play".
Unfortunately, the last version of xsane wich worked together with my slide scanner (Canon canoscan 2700F, a scsi scanner) was 0.91. All version above this crashed when I choosed the scanner in the startup dialogue.
The programs scanimage and xscanimage (belonging to sane-frontends) and kooka (from kde) are working well.
I really don't know, what information would be helpfully for you to resolve this problem. I made a file with xsane output, where I've set SANE_DEBUG_CANON, SANE_DEBUG_DLL, SANE_DEBUG_SANEI_SCSI to 128 (as explained in the sane man page) but is file has 1300 line. I'm afraid, this is a little bit to much to post the whole file without any request in this list.
I will give only some line from the middel (sane finds the scanner) and the last few lines here. "Speicherzugriffsfehler" is german for "segmentation fault" ;-)
here comes some output:

O.K. this is, what sane gives me
I can give you some information about my system
- sane backend 1.0.13-r3 (r3 is a part of the gentoo versioning scheme, but it makes no difference, what version of sane-backends I'm using, tried a lot)
- My system is a gentoo linux with kernel 2.4.22
- tekram scsi controller driver module is ncr53c8xx.o
- I also have a scsi dvd-rom and a scsi cdrw attached to the scsi-controller
- There is no difference in trying to access the scanner over network or directly
- I have another scsi scanner (an very cheap mustek scanexpress 12000SP) and this device works fine
So, that's all what I can give you at the moment.
I you need more, please tell it to me. I will try to give my best to deliver all needed information to solve this problem.
Thanks for reading the whole stuff
best regards
Thomas
