[sane-devel] Help with Canon 2700f
Hi first let me apologise for posting here but I have searched on the net and posted in two Linux user groups all to no avail. I'm running Kubutu 6.06 64 bit using Kernel 26.15.26 and so installed Deb packets from this distribution. I'm trying (very trying at times) to get GIMP to Scan using a Canon 2700F film scanner but neither Gimp nor Kooka see it, They both see the USB flat bed, From the Sane document I know that this scanner is supported by sane canon backend.This scanner shows in KinfoCenter as Below Attached devices Host scsi0 Channel: 00 Id: 02 Lun: 00 Vendor: CANON Model IX-27015C Rev: 1.15 Type: Scanner ANSI SCSI revision: 02 And my SCSI shows up correctly. From the documentation in the sane-backends-1.0.16 I found the following which seems to applie. Add the canon scanner to the /usr/local/etc/sane.d/dll.conf file: cut here # enable the next line if you want to allow access through the network: #net pnm #mustek #hp #qcam #umax canon cut here Add a canon.conf file to the /usr/local/etc/sane.d directory: cut here scsi CANON cut here In the Kubutu distro I use there is no /usr/local/etc/sane.d/dll, but there is a /etc/sane.d/dll which I assume is the equivalent in this distro. In this directory I have made a file .conf file, cutting and pasting as instructed. There was already a canon conf file in the /etc/sane.d consisting of, #canon conf /dev/scanner #/dev/sg0 and so to this I cut and pasted scsi CANON and have tried it in all possible combinations commenting out lines and removing comments, but cannot get Gimp or Koola to see it even as root. The scanner goes through its calibrate cycle on boot up. The only components of SANE I have installed are the following gimp2.0-quiteinsane libsane python-imaging-sane python2.4-imaging-sane Any help with this would be most wellcome at this point(please save me from the evil empire of windoz) John.
[sane-devel] Setup Packet Question
perhaps the usb sniffer just shows the setup packet in the return data? i mean, all those values are listed in the going down part: Request = ff Value = 8440 Index = and then later in the coming back part: SetupPacket : 21 ff 40 84 00 00 40 00 i dont think the setup packet actually comes back. can you try looking for a firmware file on your windows box that looks like these data blocks? allan On Tue, 1 Aug 2006, Tabor Kelly wrote: I feel like I understand almost all of what is happening in this log: http://tabor.taborandtashell.net/sane-fs2720u/turned_on.LOG However, I don't understand any of the Setup Packets with the bmRequestType of 0x21.

Hello, On Aug 1 16:31 marcela castro wrote (shortened): scanner Benq Saw 4300U to work with this system Suse 10.1 ... require the firmware upload. driver snapscan (package sane) ... Could you please let me know from where can I download this firmware upload and the driver snapscan? When you use YaST (our default setup tool), it will install the right software packages for your scanner (in this case the package sane is sufficient because it includes the snapscan driver). When you select your model from the model list in YaST, a Firmware upload required popup message appears which reads: - A firmware file contains software that must be uploaded to the scanner's memory. Without firmware, the scanner cannot work. Because firmware is licensed by the scanner manufacturer, we cannot distribute it. Usually the firmware file is stored somewhere on the manufacturer's CD. Alternatively, it may be possible to download it from the manufacturer's Web site. Ask the manufacturer how to get the firmware file for your particular scanner. Find additional useful information on the SANE Web site at http://www.sane-project.org/. After you get the firmware file, you must configure the driver manually. The man page of the driver describes how to configure it for firmware upload. The following command shows the man page for your driver: man sane-snapscan - The sane-snapscan man page reads: - ... For scanners that need a firmware upload before scanning add a line starting with firmware followed by the fully qualified path to your firmware file, e.g. firmware /usr/share/sane/snapscan/firmware.bin For further details read http://snapscan.sourceforge.net. - On http://snapscan.sourceforge.net you find a table with firmware file names.

I have hardware but the only problem i am facing is warmup time exceed and head moves further scan area.

This is essentially the only scanner that I can get at a reasonable price at the places that I know and, unfortunately, it doesn't seem to be supported under Linux. I would like to know if there is any possibility of having it working in the near future.

Crystle 1. what does your plustek_pp.conf look like? 2. you are doing this as root? 3. what is the io port and irq set to in the bios? allan m. allan noah wrote: ok, i remember some of this from before. try this- ditch the printer temporarily, and reboot the machine. go into the bios settings, and try each of the ecp/epp/bidirectional etc, port options, one at a time. after changing one option, boot the machine into linux and run SANE_DEBUG_PLUSTEK_PP=255 scanimage -L from the command line. check: man plustek_pp for more info. allan On Wed, 2 Aug 2006, Immanuel CRC Office wrote: No... I'm just trying to get my Plustek scanner to work, and it doesn't show up in scanimage -L, that just shows the HP printer that is connected through the scanner to my parallel port. Crystle m. allan noah wrote: Crystle: are you writing a sane backend driver? the DBG macro is part of the source used to build SANE, every existing backend uses to print warning messages, so there are lots of examples... allan On Wed, 2 Aug 2006, Immanuel CRC Office wrote: Could you explain how to use the DBG macro? Crystle m. allan noah wrote: try using the DBG macro in your backend to print some messages from within sane_init() and sane_get_devices(). then call: SANE_DEBUG_BACKENDNAME=255 scanimage -L Replace BACKENDNAME with name of your backend in all caps. if you dont see your messages, then the dll backend may not be loading your backend. try using `strace scanimage -L` to be sure. allan On Wed, 26 Jul 2006, Rupesh Tarpara wrote: Hi, I have hand held image scanner which is a USB-ACM device and uses standard ACM driver (serial communication protocol over USB interface). The device file created by driver is /dev/input/ttyACM0 (virtual serial device). Following is the build procedure I have followed. I have downloaded sane-backends 1.0.18 source and made the following changes to incorporate my device: 1. I have created a new backend source file for this device. 2. I have modified sane-backends-1.0.18/configure.in and sane-backends-1.0.18/backend/Makefile.in files to include my backend. 3. executed autoconf, ./configure, make and make install 4. all libraries were installed at /usr/local/lib/sane I modified the /usr/local/etc/sane.d/dll.conf file to include my backend name. I am using Xsane as frontend. When I run Xsane, it gives error message as no devices available --- My queries, 1) are there any backend configuration steps which I might have skipped? 2) What is the procedure frontend follows when it is executed? 3) How does the communication happens (or initiates) between Frontend backend -- device? 4) What are the steps to be followed for new backend installation? - Additional information about OS and sane version I am using. I am using RedHat AS3 OS, following is the output of uname -a [root@mypc root]# uname -a Linux mypc.home.com 2.4.21-40.EL #1 Thu Feb 2 22:32:00 EST 2006 i686 i686 i386 GNU/Linux [root@mypc root]# scanimage --version scanimage (sane-backends) 1.0.18; backend version 1.0.18 Regards, Rupesh http://www.patni.com World-Wide Partnerships.

[sane-devel] Setup Packet Question

When this failed to get me anywhere I used Search and Replace for Windows (http://www.funduc.com/search_replace.htm) to search for the first 16 bytes in Betrik's file. The only place where that 16 bytes occurs is in Betrick's file itself, and some old SnoopyPro logs I had (so Betrick didn't mess up making the file). Oh well, I will cease to worry about this for the moment. I do not think it will be an issue. -Tabor
