[sane-devel] [NEWBIE] find-scanner OK, but scanimage NOT;

[Florian Konnertz]

Hi sane people,
before I go insane, i decided to ask you to help me with your knowledge 
and sanity ;)

I have an AGFA snapscan e20, slackware 8.1 (2.4.18).

Until some days before I've been running a usb mouse (logitech optical) 
on that box. I use this (cool!) mouse now on my new box. First I tried 
to get the scanner to work at the new box, but when I uploaded the 
firmware the mouse hang.
So I decided to use the scanner with my old box to avoid this problem. 
(Both boxes same slack-8.1)

Below is  the report of the steps I took.

Thanks in advance,
and have a nice day,

Florian

3. Firmware: OK

First try:
root at groovehunter:/usr/share/snapscan# ./snapscan
Can't open scanner device at /usr/share/snapscan/agfafirm line 139.


Then:
switched scanner off and on again:

root at groovehunter:/usr/share/snapscan# ./snapscan

root at groovehunter:/usr/share/snapscan# scanimage -L

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).



cat /etc/sane.d/dll.conf

???  Should I see the device here?


root at groovehunter:/usr/bin# ./sane-find-scanner

Hhmmmmm.... ??


So, please give me a hint!
In the moment I cannot understand the principle how the whole thing 
works (if it works :) I hope, this changes until tomorrow morning;)

I will write a docu and put it on my website, so your time is in good hands.

Thanks in advance,
and have a nice day,

Florian
