Scanners -- a word of praise!

[fingers99]

I just wanted to praise whoever wrote the scanner autodetection stuff.

I've a Mustek BearPaw (OK, I'm a cheapskate) which usually takes something like 1/2 hour to set up in SuSE (and that's when I can get the evil YaST to co-operate). It's a moderately tricky device to set up because although it's a Mustek it uses the Plustek drivers.........

Anyway, Knoppix recognises it immediately and all that's necessary is to apt-get install xsane (Mustek's don't like xscanimage).

Great stuff! :D

yep.
SUSE isn't everything.
I got a story too :
SUSE even won't pass the install phase on a nforce 220D based motherboard. (while SUSE uses GRUB bootloader =>requieres more memory). Knoppix did manage to boot :P
Debian on the contrary sticks to the basics of linux...

Hello all,
I am just adding to the praise for KNOPPIX.
I couldn't get my older scanner to work
so I did put out some money for an
Epson 1660 USB 2. I work from CD so
my KDE Autostat copies in a revised file
for /etc/sane.d/epson.conf from the floppy.
But all works great and the USB 2 is
very much faster so I guess I did not
waste my money.

Best Wishes

I don't have a scanner so I don't know exactly needs to be done to get xsane working, if it will need to be restarted after loading the new conf file or what...

But as far as scripts and edits to your knoppix system, you will have to save your edited file to a writable media such as a floppy or a your persistant home, etc. and then load the file from there. When running from the cd you are using a read only media, some of the system is in ram but when you reboot all edits are gone, so you must save to a persistent hoem, a floppy, a zip disk, or a windows partition(not ntfs), etc.

Note in the second quote above paradocs uses KDE Autostart to load the fixed file from floppy, in order for that to work I think you will have to have a persistent home.

You could just manually copy the file from floppy after your system is booted.

Hi 1ijack,

The magic of KNOPPIX from the compressed cloop read only
file on the CD can be a bit hard to follow. I like doing projects
from the live CD KNOPPIX.

Here is the trick. When you get into the directory
/etc/sane.d and type ls you see blue files.
Now type ll -a
and you will see that these are not real files -- they
are links. So you cannot edit them.

What to do? Well you copy the file -- epson.conf
in to /home/knoppix.

If you try to edit it from your desktop it will say permission
denied. Bummer! The file is a root file. So from the
shell enter the command su. This will make you root.
Now you can edit the file -- if you can manage a console
editor. My favorite is vim -- so study that. :wink:
Ok, gvim started from the root prompt wil work.
Make your edits and save this file.
You may want to also save this to a floppy if you do not
have a persistent home.

Now for the weird part: In the read only directory you
cannot add new files or change the files -- remember they are
links to the CD. But you can remove the file link as root.
rm -f /etc/scan.d/epson.conf
And now you can copy your edited file there since KNOPPIX
has alowed a link for that file name.
cp /home/knoppix/epson.conf /etc/sane.d/*.*

Hard to believe but it should work. For fun -- now
go the /etc/sane.d and again type ls.
Low and behold, among all the blue files will be your
white one.

As I mentioned above, all of this can be automated
from a script. But get it working by hand first.

Let me know if you get this to work.

For the new versions of KNOPPIX live CD
Herr Klaus Knopper will allow a method
of file overlay -- translucency -- to allow
new user created files to appear as if they
are on the CD file system.

Best Wishes
