[sane-devel] [PATCH] Fix handling of SANE_CONFIG_DIR environment variable

Is there anyone here you can take a look at the patch, concerning correctness etc.? BTW, the main problem (wrong pointers to the list of config dirs) does not appear when you set SANE_CONFIG_DIR only to one directory, but only if you set it to two or more directories. Here's the debug output of current git master in that case (notice the path before dll.aliases!): reinhold at curie:~/Software/sane-backends$ export \ SANE_CONFIG_DIR=/home/reinhold/temp/sane.d:/etc/sane.d: reinhold at curie:~/Software/sane-backends$ scanimage -L [sanei_debug] Setting debug level of sanei_config to 127.

[sane-devel] SNMP detection of network scanners?
For magicolor devices, KONICA MINOLTA provides SNMP functionality to detect the scanner (existence, model, etc.) and also some of its capabilities. Is there any SNMP framework provided by sane that can/should be used, or is it completely up to me to implement the SNMP conversation? I couldn't see anything SNMP-related in the default backends, so how would you suggest to implement SNMP? libsnmp or manually implementing SNMP from scratch (as cups seems to do)? Cheers, Reinhold PS: The backend for the magicolor 1690mf (and as Ilia Sotnikov noticed probably also some bizhub devices) is progressing nicely. Currently, I'm already at a stage where the scanning is started and the data is received by the backend. Of course, there are still some things where I don't know the exact purpose of command arguments, but the most important stuff is decoded and implemented. If you are interested, the current state can be found a git repository at repo.or.cz: http://repo.or.cz/w/sane-backend-magicolor.git WARNING: This is very much work in progress, so it will probably not work for you yet, and it might even lock up your device right now!

[sane-devel] HP 8250 ADF doesn't work (patch)
Hi, I own an HP 8250 scanner, but the ADF unit doesn't work with sane. In my attempt to find a solution I stumbled upon Debian bug 521410 (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=521410). In this bug, it is reported that scanning used to work with a previous version of avision.c, but that with later versions the ADF stopped working. With the supplied log files in that bug, I decided to try to figure out what changed in the source and see if I could return the functionality. I went through every change in avision.c, going back until June of 2006, until I narrowed the problem down to a bit field which used to have one of two bits set for all ADF scanners but was later changed to only set the bits based on ADF capabilities. Unfortunately the new code which determines the ADF's capabilities excludes this scanner. There are two core problems: 1) The first is that the code is trying to determine the ADF model from the scanner, but the returned value from the scanner is not giving us enough information to determine what the capabilities are for the ADF. 2) The second is that the code added to correctly set the scanner bits for 2-pass duplex scanners sets a completely different set of bits than before. About the first problem (detecting the ADF): The code uses a byte value returned from the scanner labeled "adf_model" in the source, but the returned value is a value in the range of 0 to 2. Although the code assigns model names to these values, it seems that different scanners, with clearly different ADF units, return the same model number, so the names can't possibly be valid. How HP uses this byte is unclear, but I suspect that if it is used at all, there is a lookup table to determine the ADF features based on the scanner model. I've looked at debug logs for almost all of the supported scanners to support this conclusion. In fact, having reviewed the documentation of each supported model and its ADF capabilities, I have concluded that this byte can be safely ignored, and that knowing the base scanner model is sufficient. I implemented a simple flag, AV_ADF_SUPPORTS_DUPLEX, which I have applied to the scanner models which support duplex scanning. If I can believe the comments, this change only affects HP scanners. About the second problem (setting the correct bits): The original code, for all ADF scanners, set either the duplex (0x10) or rear scanner bits (0x08) depending on the selected ADF mode. The subsequent changes do this for only interlaced scanners (aka 1-pass scanners). The code does not set these bits for 2-pass scanners, but instead sets the lowest three bits (0x07) of the bitset3 bit field. The comments suggest that only HP scanners do 2-pass scanning, so I haven't looked at other Avision scanners. In the 2-pass case, the last three bits are set, but the duplex mode (0x10) is not. The comments in the code do not lead me to believe that the rear scanning mode exists for HP equipment, neither do the photos, debug logs, or documentation of the equipment. As a result, my change is to add setting of the duplex bit (0x10) in addition to the last three bits (0x07) (although it should be noted that these were not originally set). I also changed the setting of the bit fields to use the SET_BIT macro which seems to be the preferred way to toggle bits. While I was patching the code, I decided to clean up some clever, but confusing, code in the set_window() function. I replaced an intermediate value (adf_mode) with references to the underlying core data structure (s->source_mode). This change looks bigger than it is because of I had to fix the indenting. Now for the bad news. I have not tested this code at all. Unfortunately, my scanner is inaccessible to me for the next year, as I've moved overseas temporarily. I can only assume it would work based on the debugging output in the aforementioned bug. I realize it's kind of rude to just dump untested code on the group, but I hope you will forgive me as I don't actually have the hardware in my possession at the moment. I've put in a lot of effort to avoid breaking other scanners, but I can't be 100% sure that I've been successful. HP scanners older than the 8200 series should be unaffected by these changes, as they don't support duplexing and don't enter these code paths. However, I'm worried about the 8300 series scanners because I have not been able to find a debug log for them. This implies that they are working with the current code, but without a debug log, I can't know which code path they use. So, if possible, please test this patch if you have a ScanJet 8200 series scanner with an ADF unit. If you're an owner of a ScanJet 8300 series scanner with an ADF unit, please send me a debug log (patch or not). These are the avision supported HP duplex capable scanners: HP ScanJet 8200 (This model didn't ship with an ADF) HP ScanJet 8250 (15ppm 2-pass) HP ScanJet 8290 (25ppm 2-pass) HP ScanJet 8270 (25pp
