Comment 52 for bug 83587

Hi Miguel and Patricio and thank you both of you

Patricio : it seems kooka should not be necessary as you will see : I thought I had restarted the system but may be I did not and going back from Windows where I still work upon receipt of your mail to Ubuntu I just made a test from Applications, graphisme, and choosing scanner : my 5300C HP was identified again. I then made a testscan and it crashed. After unpluging the scanner and powering it off and on and repluging I rememberd Miguel observation not to use 150 dpi but 300 dpi and there it just worked beautifully. So for me 3 steps were necessary as explained above by Miguel :

1/ downgrade to the earlier "sane" version. Download from http://archive.ubuntu.com/ubuntu/pool/main/s/sane-backends/ the file libsane_1.0.18-3ubuntu1_i386.deb Then copy the file in the current directory of the open Terminal and execute:
sudo dpkg -i --force-downgrade libsane_1.0.18-3ubuntu1_i386.deb

2/ use the system, admnistration, user and group menu to tick the user name as authorised to scanner in "propiétés" of the user

3/ execute the file : sudo gedit /etc/udev/rules.d/45-libsane.rules and cancel by commenting (using "#") the line SUBSYSTEM!="usb_device", GOTO="libsane_rules_end"

and restart and after calling the scanner from Application, graphisme, scanner, once 5300C HP identified, change the 150 dpi resolution to 300 dpi

3 days for the scanner now I am going to work on my connextant modem !
