[sane-devel] Fail to detect the SCSI card (Problem solved)

[Stephen Liu]

Hi klaus,

Thanks for your advice.

Problem solved with following steps;

FedoraCore2
===========

As root
1) ln -s /dev/sg0 /dev/scanner
2) groupadd scanner
2) chown root scanner /dev/scanner
3) usermod -G scanner satimis (add user to group)
4) chmod g+rw /dev/sg0
5) edit /etc/rc.d/rc.local
putting following line on it
modprobe aha152x

It is done.  Each time booting the PC "aha152" is
loaded automatically.

Now I can start 'xsane' either on terminal or from;
KStart > Graphics > Kooka

In these 2 days I went through many documents on
Internet.  The more I read the more confuse I was.

I did it based on some broken information from
Internet, advice as well as on my weak recollection. 
I installed this old scanner on RH8 only once about
2/3 years ago.  I'm not very knowledgeable on its
installation as I'm not doing it daily.

Anyway lot of thanks for your continue advice.  I
expect to learn follows with your assistance.

1) modprobe -v sg
What is its function.  There is no output here (on
running it)

2) How to ckeck the kernel whether it supports ISA
card and how to detect ISA SCSI card without
installing additional tools, such scan isapnp tools,
pnpdump, etc.

3) Can you recommend an "ebook" software from
OpenSource" as there are many of them on Internet. 
What I expect to have is binding scaned images as
book, re-arrange/resort its pages, simple editing
tools to add notes, etc.

TIA

B.R.
Stephen
