I am having a problem scanning with our Epson Perfection 2400 scanner. This
problem only occurs when I use Kooka (doesn't matter whether it's the version
that ships with Fedora Core 2, or the one on CVS HEAD.) I tried scanning an
image earlier using xsane, and it worked just fine.
Here is a link to an image that I Just scanned (using "xsane", to show that
the scanner works just fine:
When I start any version of Kooka (for this experiment, I will start Kooka
while su'd into root. This is what the GUI looks like:
Then I proceed to do a "Preview Scan" This is what the GUI looks like then:
If I try to do a "Final Scan", this is what the GUI looks like:
You will notice that these are identical screen shots. This is because
whether I choose "Preview Scan" or "Final Scan", nothing appears to be
The only configuration file I could find was in "~/.kde/share/config" I tried
deleting that and retrying what I described above, to no avail.
At the following location, you will find a tarball of the terminal window
outputs that I got when I tried a Preview and a Final scan. In the same
tarball, you will find straces of attempts at Preview and Final scans.
Root is the group and user of /proc/bus/usb/001/013
Also, root does have read, write and execute permissions on this device.
One thing I just thought of: I can't remember for sure, but should I have
a /dev/scanner? I can't remember if I had one in the past, or if that is
relevant with a USB scanner. All I know is that I don't have one now.
Operating System: Fedora Core 2, All Packages installed, All official Updates
installed (Except the kernel)
QT: 3.3.3 from TrollTech source tarball
KDE: CVS HEAD
QT and KDE paths are both exported in my ~/.bash_profile. I did not overwrite
the FC2 default KDE.
In closing, this same scanner, using Kooka from the CVS HEAD version of KDE,
used to work perfectly, never giving me a moment of trouble. Like I stated
earlier, and proved with an example for your viewing, this same scanner that
does not work with kooka, does work just fine with xsane.
I will be glad to answer any questions that this problem might require.
Have a Great Day
