[sane-devel] Remote access to Pulstek OpticBook 3800
In order to do something to make my Pulstek OpticBook 3800 scanner work with sane I'd like to offer sane developers a remote access to my dev-desktop with scanner attach to it and with webcam+sound video streaming showing this scanner. If you send me ssh public key and login, I will grant you root access there and tell where to watch webcam streaming. Just for note: I've already reported about Pulstek OpticBook 3800 http://lists.alioth.debian.org/pipermail/sane-devel/2013-April/031220.html USB sniff etc. We found out that it uses GL845, basic GL845 support were added to sane after that, but it did not make it work properly. It do not even move carriage as it should but makes unpleasant sounds instead. A year ago 3800 was the only economy class device allowing scanning books without opening them wide. I think it is important to have this device supported by linux. There is no alternatives for it thus I can't just simply replace it. signature.asc Description: This is a digitally signed message part. -- sane-devel mailing list: sane-devel@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/sane-devel Unsubscribe: Send mail with subject unsubscribe your_password to sane-devel-requ...@lists.alioth.debian.org
[sane-devel] Current status of Pulstek 3800 on git
I've built current git version and try it with my Pulstek Opticbook 3800. export SANE_DEBUG_GENESYS=255 export SANE_DEBUG_GENESYS_LOW=255 export SANE_DEBUG_GENESYS_GL646=255 export SANE_DEBUG_GENESYS_GL841=255 export SANE_DEBUG_GENESYS_GL843=255 export SANE_DEBUG_GENESYS_GL846=255 export SANE_DEBUG_GENESYS_GL847=255 export SANE_DEBUG_GENESYS_GL124=255 scanimage -d genesys --resolution 75 --preview --mode Color 2preview.log preview.pnm What does it do: 1. Turn lamp off (It is on by default after turning it on) 2. Turn lamp off 3. Move caret a little bit (just several mm) from right to left 4. Make a strange sound 5. Pause longer than usual 6. move caret back, turn lamp off between each action there is notable pause. In the attachment there is a debug log from genesis backend, taken while scanning.

[sane-devel] Pulstek OpticBook 3800 - problems with openning device on 1.0.23+
Since I added preliminary support for GL846 a couple of months ago, you'd rather declare your scanner as a GL846 one like the canon_formula101_model. I've tried... scanimage -L does not list scanner at all in this case O_o Very strange for me... :-((( In order to test a newly compiled version, you can run it with the attached script (edit it to adapt it for the exact location of sane sources on your PC). The debugging output (preview.pnm and preview.log) will help the development and fixes of the backend part for GL846. see preview.git.as.canonf101.gl846.log there are also two files that shows how differently works gl847 in git and 1.0.22 I have starting to add preliminary code to handle the GL845 in the genesys backend. I'll commit it in git in about a week. Meanwhile I have updated sane-find-scanner to better detect genesys ASICs. I am interested by the test of the very latest git code on your scanner. You don't have to do 'make install' to try the new sane-find-scanner version, just run ./sane-find-scanner from the 'tools' subdirectory. Current git gives two different behavior when I try to scanimage. 1. It turn off lamp, turn on lamp, move head little bit forward, move it back, stop 2. Just turn off lamp and all there is a debug output of both variants. // Sorry for being so late, I misread your message, and decided that you will make ASIC detect in future and were waiting for test request, wondering why does it takes so long. And only now I reread message and understood that all already done by now, long time ago... Sorry once again... -- next part -- A non-text attachment was scrubbed...

[sane-devel] Pulstek OpticBook 3800 - problems with openning device on 1.0.23+
since the ASIC used is a GL845, you should not try forcing it to GL847. They are really different, and nothing will ever work. If you look at the GL845 datasheet, you'll see it is really close to the GL846. So close in fact that the same code should be able to run both. 1. I've build git version with setting GL846 chipset to 3600 clone in the model description. It gives the same result as I wrote before 2. In 1.0.22 GL847 worked for me well. It stopped working in 1.0.23. So I think this is not an chipset issue. (if at least there were no great changes in genesys_gl847.c) What do you mean by worked well? Since chip a GL845, it won't work with GL847 code. It did not fail on scanner detection, it turn off the light and move the scanner head... In 1.0.23 it fails on initialization... Were there great changes in genesys_gl847.c between 1.0.22 and 1.0.23? In order to test a newly compiled version, you can run it with the attached script (edit it to adapt it for the exact location of sane sources on your PC). The debugging output (preview.pnm and preview.log) will help the development and fixes of the backend part for GL846. Ok. Will do it in several days when I am near the scanner again...

That's all I did, and same trick makes sane at least try to move scanner's head
in 1.0.22
libusb:002:007 is opened, then libusb:002:006 is tried.
Oh... I should be more attentive. I did not noticed that.
How many scanners do you have?
Actually my notebook has webcam and fingerprint scanner in it.
the first one is detected by sane as an acceptable input device (but I've never
tried to use it this way)

All my previous efforts I did with libsane 1.0.22 that comes with debian. I've tried to do the same trick with git version and with 1.0.23 and did not managed to do it.

did you see my email on the list? Yes, for technical reasons, previous mail I've sent did not properly get to the list, so I resend it without editing it. I wrote that letter before your letter, but it get to the list some days later... I tried to understand the protocol a bit. However, I'm not familiar with USB. If I had time, I guess I would try to talk to the GL845 using python (pyusb) in order to understand it better. If you stop working on the driver, please let me know; then I'll start learning USB. Eh... I am not a driver developer at all... I will do my best when I have time and energy to get it to work, but this might take a long while... I've created a branch at github https://github.com/dhyannataraj/sane-backends-gl845 in order to work on this problem. But I've met some strange problems (I will write about them in another letter) so after the creating of a branch the development stopped. I think we should put your annotated usb sniff in a wiki there, in order to have all staff together.

Hello, to my knowledge, regarding bdcDevice, we currently have: GL843 devices bcdDevice 5.00 GL846 devices bcdDevice 6.01 GL847 devices bcdDevice 6.03 GL124 devices bcdDevice 7.01 So the the 6.05 value you have is a hint that your scanner doesn't use a supported genesys ASIC, probably a GL848 or GL123. By comparing the datasheet of these ASIC, you'll find register that aren't shared, and if you find the use of such registers in log, you'll be able to identify the ASIc used. Or find a 38x26 pins IC, labeled GLnnn, where nnn will be the ASIC version. It is GL845. Other ICs are (just not to open it second time) ESMT \n M12L64164A- \n AZV1P22P5 and WM8196SCDS \n 23AAMDD Also I've found GL845 datasheet at http://www.dz863.com/datasheet-827931563-GL845_High-Speed-Usb-2.0-2-in-1- Scanner-Controller-With-Adf/ So as I can understand I should clone some genesys_gl84?.[ch] and start to adapt it to 845 accoding to UsbSnoof log and datasheet. What file is better to clone? 843 according to datasheet has registers up to 0xAE, 841 up to 0x87. for 847 there is no datasheet. and 845 uses registers up to 0xFF. So I think it is better to start from 847. Am I right? And then from what point it is better to start? At least I should make the head not trying to move out of phisical limits. I do not want it to be demaged... I think it is good point...
[sane-devel] Pulstek OpticBook 3800
the first step is to find the exact ASIC used in your scanner. Can you post an USB log of a preview done with the windows driver ? http://lj.shaplov.ru/2013/UsbSnoop.log.gz http://lj.shaplov.ru/2013/UsbSnoop.parsed.log.gz (parsed with usbsnoop- gl847.pl as I found in this mail list) This log is sniffed right from the point of when scanner were turned on. And also the result of lsusb -v ? lsusb.log in attach Is there a chance you can IC through the glass when the scanning head is moving ? IC is for microchip? Then there are 27ANG9K G4 \n ACT 04 and UTC \n 78D 05L \n 01 PGT0 The first one has about 14 legs, the second one only two. There are two chips with first sign and two chips with second sign on the board that attached to the head. Then adding this scanner will be like you started it, but you'll also have to add specific entries for sensor, motor and gpio which change from device to device. The needed values will have to be deduced from USB logs. I've already started to view USB log and found matches with GL646 spec, but I am still not really good with it, and also I still do not understand how does such simple operations, as writing some bits into LAMPPWM (for example) from USB log corresponds with the code from genesys_gl847.c The code path will had to be modified for the new defines. BTW there is no CCD sensor support currently in gl847 code, only CIS sensors are handled. That would need to be changed firt. What is CCD and CIS? :-) -- next part -- A non-text attachment was scrubbed...

[sane-devel] Pulstek OpticBook 3800
Hi! I've recently bought Pulstek OpticBook 3800, hoping that it is almost the same thing as 3600, and I wont need much configuring with it. This hopes died when I did sane-find-scanner, it said found USB scanner (vendor=0x07b3 [PLUSTEK INC], product=0x1300 [USB2.0 SCANNER], chip=GL847) at libusb:001:020 and 3600 is GL841 :-( What did I do: I've cloned Genesys_Model plustek_3600_model in backend/genesys_devices.c replaced GENESYS_GL841 with GENESYS_GL847, added correct vendor and product id for this clone in device list there, built and installed it, and also added vendor and product id into /etc/sane.d/genesys.conf Result was the following scanimage makes the scanner move it's head (not always sane, sometimes it tries to move out of device physical limits) and turn the lamp on and off. Scanning goes with turned off lamp, and the result file if always filled with 0x00, even if i put external light source over the scanner. This is my limits of what I can do myself without your help. I did not found any info about how to turn some debugging output (-v -v -v -v -v does not give much information about what sane is trying to do with the scanner) I did not found any guides about how to debug devices in such cases. If you can help me with these question, or even can guide me through the debugging process, this would be great. As I can understand GL847 chip is supported by SANE and we should do calibration and other staff like these... What I should do first?
