I had made an initial post, then posted a debug run which ended up in a different thread because I subscribed in digest mode initially so I couldn't reply. Anyway, I saw a tiny bit of activity on my debug file in my Apache logs, but I don't really know who looked and I haven't heard anything.
To recap, it looks like I need to set "option scsi-buffer-size-min 32768" to something bigger. I'm seeing errors like "ERROR: too small scsi buffer (32768 bytes) to send gamma data" and "ERROR: scsi buffer is to small for one shading line, calibration aborted" and "scanimage: sane_start: Out of memory" When I try to increase the scsi-buffer min size even to 33768 though, I get "ERROR: sane_start: umax_scsi_open_extended returned too small scsi buffer" then "scanimage: sane_start: Out of memory". With this value increased it won't even start the calibrate (the scanner never moves). With the 32768 value I can scan a small area of RGB data successfully, or do a full gray-scale or lineart scan. At some point though I don't have memory enough for a larger RGB scan. I'm not sure how to change this. The operating system is OpenBSD 3.8, the SCSI card is an Adaptec 2940u. So, the files: At http://128.119.200.7/debug.txt is the result of doing a small area RGB scan which worked. (scanimage -v --resolution=300 -y 100 -x 100 > test1.pnm 2>debug.txt) At http://128.119.200.7/debug2.txt is the result of a larger area that didn't work (scanimage -v --resolution=300 -y 200 -x 200 > test1a.pnm 2>debug2.txt) At http://128.119.200.7/debug3.txt is the result of setting option scsi-buffer-size-min to 33768 and trying the larger scan again. My umax.conf file is at http://128.119.200.7/umax.conf if that might be of use, and there is mention of an Astra 2200 on USB in there because I also have one of those. I don't have it here though, so I haven't tried it on SCSI (lately, on this machine). Alan __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
