Firmware for Epson 3490 Perfection does not upload to scanner

Hello,

I am busy trying to get a brand new Epson Perfection 3490
PHOTO at work under SANE.

I am running on Debian unstable, scanimage (sane-backends)
1.0.18; backend version 1.0.18.

One of the problems with this scanner are the many
contradictory messages, which sometimes 
say that it is possible to make it work, sometimes it seems
other people have the same 
problem, but it never seems clear what the real solution to
the problem is. One extra 
problem is that the proprietary parts of the system are only
distributed as rpms.

Currently, I have my system configured for the epkowa
driver.

After testing the system also under Windows XP, I have come
to the conclusion that the 
problem sits somewhere in the uploading of the firmware file

/usr/share/sane/epkowa/esfw52.bin. The epkowa.conf file is
configured to find this one, and 
it is available, but when running 

SANE_DEBUG_EPKOWA=128 scanimage

I get the following messages as part of the output :

[epkowa] sane_init, ># Change to the fully qualified
filename of your firmware file, if<
[epkowa] sane_init, ># firmware upload is needed by the
scanner<
[epkowa] sane_init, >firmware
/usr/share/sane/epkowa/esfw52.bin<
[epkowa] attach_one(firmware
/usr/share/sane/epkowa/esfw52.bin)
[epkowa] EPKOWA SANE Backend 1.0.18 - 2006-05-22
[epkowa] attach(firmware /usr/share/sane/epkowa/esfw52.bin,
1)
[epkowa] attach: opening firmware
/usr/share/sane/epkowa/esfw52.bin
[epkowa] attach: open failed: Invalid argument

These are its ownership and access modes.

-rw-r--r-- 1 root root 64000 2006-06-20 21:49
/usr/share/sane/epkowa/esfw52.bin

The following step would have been that I compiled the sane
software myself, and adding more 
messages, but before I do this I would like to know if there
are other people with the same 
scanner, and if they have succeeded in getting it to work ?

Regards,

Jurgen Defurne

This scanner works quite well with open source snapscan
backend.
Have you tried it?

Try `alien -c` on the RPMs and let me know how that works

Eh, that epkowa.conf file doesn't understand firmware file
locations.
The backend's interpreter "knows" where to look
for the firmware file.
Rip out that firmware file line and try again.

On the other hand, if you try the snapscan backend you will
need that
firmware line, but it should be in snapscan.conf, NOT in
epkowa.conf.
