Search for "release" and/or freeze in the archive. Or check the
Changelog in CVS for messages like this:

**  Release of sane-backends 1.0.12. End of code freeze **

You can commit whatever you want :-) By the way, I changed
backend/Makefile.in to not link hp5400 to sanei_config2.lo. That
shouldn't affect your backend because you don't use that code at all.

If you like, you can use the Hewlett Packard test drive at
testdrive.hp.com. They have several Linux, *BSD, Tru64, and HP/UX
machines. But setting this up to work at least semi-automatically
requires quite some work and some non-linux Unix knowledge :-/

So if you don't want to invest some time into learning how
crappy^h^h^h^h^h^h differnt from Linux some systems are, compiling
with Linux (and maybe a BSD if you have it) is ok. I'm using the
testdrive from time to time and will complain if something doesn't work.

The debug macros ARE complex if you use more than one compilation unit.

The freeze is over :)

SF.net has a compile farm (never used it), otherwise there's the
HP/Compaq testdrive (http://testdrive.hp.com) but Henning knows more
about this one than I do :)

[sane-devel] CVS freeze ?

[Thomas Soumarmon]

Hi everybody,

Sorry for the silly question but I have been a bit SANE-offline for a while, 
and I didn't find quickly the answer in the mail archive.


I wanted to commit into CVS some changes about the hp5400 backend.
Is there a CVS freeze at the moment or may I do it ?

And before that, is there a compile farm or some kind of, to verify at least 
it compiles ok on various platforms before commiting it ?



Thomas.


PS : changes are not functional, they are "only" to make a synchronization 
between hp5400backend sourceforge CVS project and SANE CVS project.

PS2: I have been messing around a lot before finding the DEBUG_NOT_STATIC 
trick to avoid the missing symbol sane_debug_hp5400_call !!!

[sane-devel] Please test sane-backends (and sane-frontends) on non-mainstream os and platforms

[Henning Meier-Geinitz]

Hi,

I'd like to update the list of platforms SANE can be compiled and used
on. There is a temporary file with the latest updates here:

http://www.meier-geinitz.de/sane/tmp/sane-support.html

If you've successfully compiled and/or tested sane-backends 1.0.12
and/or sane-frontends-1.0.11 on any of the mentioned platforms that
isn't up-to-date yet, please contact us. Also if the platform is
mentioned, but there is a question mark for SCSI or USB support,
please tell us if you were able to actually scan with a real scanner.
If you have access to a platform but it has no scanner please try at
least the test backend: "scanimage -d test -T".

Any other corrections or additions are also welcome.

Thanks,
  Henning

[sane-devel] Canon Lide 30 backend

The Lide 30 is supported by the plustek backend.

Try "SANE_DEBUG_PLUSTEK=255 scanimage -L" to find out what's wrong.

The plustek backend is the right one. You can find out about which
scanner is supported by which backend by using the scanner search
engine: http://sane.informatik.uni-freiburg.de/cgi-bin/driver.pl

The setup of the config file is explained in man sane-plustek. But
ususally this should work without manual intervention. Also check that
"plustek" is in dll.conf.

Thanks for the information. I'll add links and update the list.

The dll backend can either load other backends dynamically (on demand)
or all the backends are linked into sane-dll (preloading).

Last but not least sane-dll can be linked statically to the frontends
(inclusing all the preloaded backends).

That's shared but not dynamic.

I did so.

Ok.

Ok, thanks :-).

Thanks again for your help!

[sane-devel] ScanJet 4100C

[Lee Morgan]

Hello,

I have RedHat 8.0 installed, when I run scanimage I get the following result:

[root@shodan sane.d]# scanimage -d hp:/dev/usb/scanner0
scanimage: open of device hp:/dev/usb/scanner0 failed: Invalid argument

I have compiled and installed sane-backends-1.0.12 and used the 
sane-1.0.9.hp.1.01 source.

The scanner is detected at /dev/usb/scanner0:

[root@shodan sane.d]# sane-find-scanner
# Note that sane-find-scanner will find any scanner that is connected
# to a SCSI bus and some scanners that are connected to the Universal
# Serial Bus (USB) depending on your OS. It will even find scanners
# that are not supported at all by SANE. It won't find a scanner that
# is connected to a parallel or proprietary port.

# If your scanner uses SCSI, you must have a driver for your SCSI
# adapter and support for SCSI Generic (sg) in your Operating System
# in order for the scanner to be used with SANE. If your scanner is
# NOT listed above, check that you have installed the drivers.

sane-find-scanner: found USB scanner (vendor = 0x03f0, product = 0x0101) at 
device /dev/usb/scanner0

But the product string is not reported when i cat /proc/bus/usb/devices:

T:  Bus=01 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#=  2 Spd=12  MxCh= 0

S:  SerialNumber=00MY8BH535KN

E:  Ad=83(I) Atr=03(Int.) MxPS=   1 Ivl=250ms

The scanner is a ScanJet4100C.

Where am I going wrong?  Is this a problem with the scanimage?

Lee

[sane-devel] Canon Lide 30 backend

[Michael Rasile]

Greetings!
Am trying to get my USB canon Lide 30 scanner to work under Gentoo. USB has 
been compiled into the kernel and when I do sane-find-scanner, the scanner is 
found. However, when I do scanimage -L the scanner is not found and therefore I 
am unable to use xsane. I was wondering what backend I should be using for this 
scannerand how should this be setup in /etc/sane.d/ I have tried everything, 
editing the canon.conf and the plustek.conf. I know the scanner works because 
when I was using Mandrake 9.1 I didn't have a problem setting it up. I would 
like to continue to use it under Gentoo. Any suggestions will be greatly 
appreciated. I've read a great deal about this, but nothing seems to help.  
Thanks for anything.

I'll play with the code a bit, and come up with more detail.
