Oi,
I have tried to compile ISCAN 1.10.0 (from iscan-1.10.0-3.tar.gz from
the Epson-Kowa web site) on the current Cooker of Mandrakelinux. At
first there is gcc 3.4.1 which needed some small changes in the code.
One has to apply the attaced patch. In addition one has to install the
headers for the needed libraries:
urpmi libimlib1-devel libsane-devel libltdl-devel
As SANE is version 1.0.14 I have also edited the line
V_REV=12
to be
V_REV=14
Then I have compiled and installed the package.
Unfortunately, ISCAN did not work correctly:
1. "scanimage -L" shows the Epson Perfection Photo 2450 as working with
the "epson" driver (which is the ISCAN version now). One can scan with
XSane, but only in the usual flatbed mode. When trying to use the TPU,
already switching to the TPU freezes XSane for a minute or so. When
trying to scan (Preview), XSane freezes for some minutes and then there
is an error message, telling that there is a communication problem with
the scanner andthe console from which I started XSane appear the messages
------------------------------------------------------------------------
[epson] You may have to power on your TPU
[epson] Also you may have to restart the Sane frontend.
------------------------------------------------------------------------
The TPU light does not turn on. When switching back to flatbed mode all
works normally again.
2. If the Epson Perfection 1260 Photo is turned on, the "epson" backend
(both the original SANE one and the ISCAN one) hangs for several minutes
and then even the also connected Perfection 2450 is not detected. The
ISCAN "epson" backend produces the message
------------------------------------------------------------------------
[epson] ident failed
------------------------------------------------------------------------
on the console where "scanimage -L" was called.
3. The "epkowa" backend does not recognize the Epson Perfection 1260
Photo. The scanner is OK, as it works without problems with the
"plustek" backend. Commenting out the "plustek" backend in dll.conf does
also not help for "epkowa" recognizing the scanner. Configuration: only
"usb" in the epkowa.conf file.
4. "epkowa" recognizes the 2450, but the startup of XSane takes ages and
are always "Failed to obtain value of option monitor-button: Error
during device I/O" messages. A Preview scannes gives "Failed to start
scanner: Error during device I/O" after around one minute frozen.
5. The GUI "iscan" does not work at all. It says "Could not send command
to scanner" before opening its main window, even if "scanimage -L" finds
scanners and one can scan with XSane. When using the 2450 with the
"epkowa" backend, the main window opens after a longer time and one can
switch the flatbed/TPU option (dreeses iscan also for a minute or so),
but trying to scan gives "Could not send command to scanner". debug log
file is attached. Note the comments in the "#####" lines which I have added.
Software versions (all are Cooker packages):
SANE 1.0.14
kernel: 2.6.6-0.rc3.1mdk
