Re: [sane-devel] SANE; scanning with LIDE series works under Win, NOT under Lx
Hello Cedric,
Also check in your home directory .sane/xsane files, maybe removing .xsane
and start again xsane could help.
Also if installed sane frontend, xscanimage could be helpfull to scan.
Regards,
Gerard
Hi Cedric,
For someone who claimed not to be a techie 2 days ago, you're doing
remarkably well.
- ICM Profile: http://linuxforums.org.uk/index.php?topic=10200.0
On linux, debug and log files are usually sent to /var/log. There's no
fixed sane debug or log file as far as I know.
Try this from a terminal:
$ SANE_DEBUG_SANEI_USB=80 xsane

Thanks a lot Stijn and Allan ! I made some progress.
Here goes:
_Background_:
sane and libsane version 1.0.23 on Ubuntu 14.04.2
scanner Canon LIDE25 works under Windows but not Linux
scanimage functions perfectly with scanner in identical conditions
under Lx.
It turns out that just like for this post
http://askubuntu.com/questions/599694/scanimage-works-but-xsane-or-any-other-ui-does-not
on askubuntu.com, I am running 'tlp' for power saving optimization. I
applied the post's author's solution by tweaking the 'tlp' config
file, so that USB autodisable would not affect my LIDE25
(0x04a9:0x2220).
After applying the change to the tlp config file, I checked it from
terminal:
$ cat -n /etc/default/tlp | egrep USB_BLACKLIST
173#USB_BLACKLIST=: :
178USB_BLACKLIST=04a9:2220
187USB_BLACKLIST_WWAN=1
Result:
'simplescan' now works for the first time in 2 months or so (though it
seems awfully slow to me).
'xsane' (the frontend I favor) gives me:
Error during CMS conversion: could not open scanner ICM profile.
The above error message appears when I launch 'xscan', when I try to
change any setting and when the scan is over.
Trying to scan, the scanner goes through all the moves at a normal
speed) but scan everything blank.
So I tried four things:
*1)* Following another post cid:part2.06040302.04030204@gmail.com, I
created the new rule:
$ sudo vi /etc/udev/rules.d/40-libsane.rules |
ATTRS{idVendor}== 04a9, ATTRS{idProduct}==2220,
ENV(libsane_matched)=yes|||
$ sudo chmod 644 /etc/udev/rules.d/40-libsane.rules
'simplescan' 's behavior is unchanged. It scans in mode gray, color.
All good.
Relaunching 'xsane' I did NOT get any more error messages. However,
although 'xsane' launched and allows the scanner to do previews and
scans without complaining, EVERY preview or scan comes out blank, even
after reboot.
*2)* I set my debug log level to 80 (don't really know what level
between 1 and 128 I should use here)
$ SANE_DEBUG_SANEI_USB=80
$ export SANE_DEBUG_SANEI_USB
However I know neither where log files are located, nor how I should
post them for review.
Perhaps s.o. can help me with hints on that.
*3)* I edited the sane.d genesys.conf file to include a reference to
Canon LiDE 25
sudo vi /etc/sane.d/genesys.conf
# Canon LiDE 25
usb 0x04a9 0x2220*
4)* Following Allan's suggestion I checked whether my bios/kernel
relies on
xhci_hcd
It does not, apparently. It seems to rely on 'ehci-pci' as seen from
the command
$ dmsg | tail
ran upon plugging my LiDE 25 scanner onto the 7-1 usb port.

I believe I do not have any USB3 issue. I simply do not have USB3
ports, just two USB1.1 and two USB2 ports.
Nevertheless knowing that power management is also effected at kernel
level, via the usbcore.autosupend parameter and I did:|
$ modprobe usbcore autosuspend=-1
|That did not have any benefical effect and I reversed the action:
|
$ modprobe usbcore autosuspend=2|
Can somebody further suggest something ?
Also I need help with the debug log files. Where are they located and
how do I post them ?
Thanks.

[sane-devel] Accessing HP Scanjet 4070 Photosmart Scanner - Update to reduce size to below 100 Kbytes
Present Configuration Hardware: A DIY “Hackintosh” Mini ITX Computer; Gigabyte GA-H87N-WIFI motherboard, Intel Core i7 4770K CPU, 16 GB RAM, Samsung 840 EVO SSD 250 GB, in Thermaltake SD101 case. HP Scanjet 4070 Photosmart Scanner Software: Mac OS X 10.10.3 “Yosemite” with boot software by tonymacx86.com http://tonymacx86.com/ What Works: Scanner works perfectly with alternate computer Macintosh PowerPC G5 using HP “Image Zone” software. What Does Not Work: 1. Scanner used with latest HP Scan App installed on the “Hackintosh.” Following error message appears: 2. Attempt to use SANE software to access scanner from the “Hackintosh.” Have downloaded all relevant software from the following websites: http://sourceforge.net/projects/hp3900-series/ http://sourceforge.net/projects/hp3900-series/ ; http://www.ellert.se/twain-sane/ http://www.ellert.se/twain-sane/ (binaries only) The SANE Preference Pane is installed and working. The configuration file for the hp3900 scanner is checked, as shown: I did click the “Configure” button, but there was no apparent change, i.e. the button did not light. (If the “Saned” button is clicked, the resulting field is empty. Double-clicking the hp3900 item shows a list which includes the HP 4070 scanner, so I assume it is the correct selection.) In the hp3900-series_0.12” folder downloaded from the first website linked above, there is a file called “INSTALL.sh” and another called “COMPILE.sh” which look like Terminal scripts. I tried double-clicking each one in turn. The result was that the Mac OS “Terminal” app opened and showed these error messages: Apparently the Terminal app is not happy with the “test: -eq:” program statement. I know nothing about C programming. Can you help with this? Please know that I had one success with all the above: If I run the Terminal command “scan image test.pnm” from this website http://www.ellert.se/twain-sane/faq.html, I do in fact get a correct scan operation and a “.pnm” image on my hard disk. However, I have no idea how to proceed since the linked page goes on to treat a failure, and no words at all about what to do if it succeeds! I attempted to use Graphic Converter (version 9.7) File/Scan mode, which offer the options of “Scan with Image Capture,” “Scan with TWAIN…”, and “Select TWAIN Scanner Data Source…” but none of these work; device is not shown in any of the three windows, as well as in Preview and Apple’s Image Capture. This in spite of the fact that the 4070 Scanner shows up in my Mac OS X “About this Mac/System Report” list, as shown below: Bottom Line: I have no idea where to go from here! Please help if you can.

[sane-devel] Setting Options Via sane_control_option(...)
I'm writing a custom frontend for a scanning project in C++ and am about 80% complete. I've been able to get this far by reviewing the scanimage and test code included in the source and whatever examples I found on the web. Hopefully someone can nudge me in the right direction. Sane, scanimage, and xsane are configured and running properly on my test system (using an Epson Perfection 636 and a Canon LIDE220). In my frontend I've got the device selected and opened and can make repeated scans, however the images I'm saving (in PNM format) aren't what I'm expecting. I'm pretty sure it's due to not setting some of the options properly prior to the scan. So my question is - what settings to I need to set to prior to doing a scan to: - set the mode (color or gray) - set the bit depth of the scan (to largest supported by scanner) - set the scan area (all scans for this application are going to be for a fixed area) Are there some straight forward examples on how to set these options? I've looked through the scanimage.c code and can't track down exactly where it handles the --mode Color command line option. The code I'm (unsuccessfully) using now to (attempt to) set these during program startup is below: // -- // taken from epson sane driver #define OPT_RESOLUTION 10 #define OPT_TL_X 25 #define OPT_TL_Y 26 #define OPT_BR_X 27 #define OPT_BR_Y 28 #define OPT_MODE 2 #define OPT_BIT_DEPTH 3 // set photo option SANE_Int saneIntVal; saneIntVal = 300; sane_control_option( sHand , OPT_RESOLUTION , SANE_ACTION_SET_VALUE , saneIntVal , sane_info ); saneIntVal = 8; sane_control_option( sHand , OPT_BIT_DEPTH , SANE_ACTION_SET_VALUE , saneIntVal , sane_info ); saneIntVal = 1; sane_control_option( sHand , OPT_MODE , SANE_ACTION_SET_VALUE , saneIntVal , sane_info ); saneIntVal = 0; sane_control_option( sHand , OPT_TL_X , SANE_ACTION_SET_VALUE , saneIntVal , sane_info ); saneIntVal = 0; sane_control_option( sHand , OPT_TL_Y , SANE_ACTION_SET_VALUE , saneIntVal , sane_info ); saneIntVal = 200; sane_control_option( sHand , OPT_BR_X , SANE_ACTION_SET_VALUE , saneIntVal , sane_info ); saneIntVal = 200; sane_control_option( sHand , OPT_BR_Y , SANE_ACTION_SET_VALUE , saneIntVal , sane_info ); // -- Thanks in advance - any help would be appreciated. -- 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
