[sane-devel] LiDE 90 Calibration
Hello, It seems that in Windows snoop calibration of LiDE 90 is done with half CCD even if scanning is in full sensor resolution. Is it so in sane ? If not, is it usefull to implement it ? Where to do that ? Regards Guillaume
[sane-devel] Perl Bindings

Would you like this to be a part of the SANE project, or should I start a new project (probably on Alioth)? It is tricky testing things, given the necessity for the correct hardware. How does SANE handle tests? Im am not aware of any formal test requirements. The test backend is a invaluably useful tool for testing: You get more or less any sort of device options; you can see if your bindings properly handle things like enabling/disabling of options, if you get the type conversion between Sane and Perl data types properly done etc etc. You even get perfectly reproducible, noise free, scan data :) Additional tests with real-world devices are also useful, because the test backend can of course not emulate the behaviour of every scanner. The Python bindings for Sane (part of PIL) for example had for years a bug in the higher components that prevented the retrieval of the backside image from duplex scanners, because sane_cancel was automatically called after an image was completely read.

to parallels and am functioning. I'll start w/ an empty bed and go from there. bob On Fri, Aug 22, 2008 at 1:16 PM, Dennis Lou dlou99 at yahoo.com wrote: Well, I'm very confident somebody can do something with the logs and get it working. Whether that person is me depends (that was my first time doing a scanner). But even if that person is not me, the SANE guys are pretty smart from what I've seen and consumer-grade scanners seem pretty well understood at this point. Especially if the protocol isn't much more complicated than the MF4270, then I'm pretty sure I can get something going. BTW, where are you located? I'm in the Silicon Valley. -Dennis - Original Message From: Bob Dronski dronski at gmail.com To: Dennis Lou dlou99 at yahoo.com Sent: Friday, August 22, 2008 10:40:15 AM Subject: Re: [sane-devel] Canon MF4140 Dennis, I've got a crazy day or two ahead of me. I'm going to really try to get you something tonight or tomorrow. Do you think the odds will be good to get the driver working if I get you the data (and I presume a few more dumps)? Just trying to prioritize my time. If you're not sure, I need to get it to you ASAP, as I only have through thursday to return easily. If you're pretty confident, I'll believe in you and not worry about the date. take care, bob On Aug 22, 2008, at 12:15 AM, Dennis Lou wrote: Great, thanks! 1. Unplug the device 2. Install the Canon drivers 3. Install a USB sniffer. I used SniffUSB v1.7 because my VM is Win2k. You can certainly do better if you are running a more recent version of Windows. 4. Plug in the device and direct it to the virtual machine (select the device from the Device menu in VMWare) 5. Start the USB sniffer (on mine, there are four possible devices/subdevices; I select Canon MF4200 Series and click the Install button) 6. If you are using XP or Win2k, click Start-Programs-Accessories-WindowsImaging then File-Acquire 7. Pick 75 DPI, grayscale and select a small area to scan, preferably full width and minimal height then hit Scan. 8. Save the log file. In SniffUSB 1.7, this means clicking the Uninstall button, copying the log file somewhere else, then clicking the Delete button. 9. Repeat steps 5-8 (possibly step 4 if your setup is as finicky as mine) using different color and dpi settings and different areas. 10. Send me and/or the SANE list the log file(s). Thanks again for your help. -Dennis - Original Message From: Bob Dronski dronski at gmail.com To: Dennis Lou dlou99 at yahoo.com Sent: Thursday, August 21, 2008 2:47:26 PM Subject: Re: [sane-devel] Canon MF4140 Dennis, May have missed the message.

[sane-devel] udev device permissions (MODE=###) is ignored but OWNER/GROUP not
On Sat, Aug 30, 2008 at 12:16:02AM +, Kanito 73 wrote: Concretely the problem is the device permission, it is set to rw-r--r-- no matter what permission I set in the udev rules file... It sounds like your udev rules are wrong somewhere. If your specified mode is ignored then it may mean that udev matches on a _different_ rule and executes that, ignoring the rule you modified. See man udevadm, specifically the test mode, to see what udev is doing for your device. Nick.
