SuSE Linux: Version 7.3
You have successfully set up and tested your scanner with YaST2, but it can not be accessed with a scan program such as scanimage or Kooka.
A comment in the configuration file has been read in by mistake.
Delete the comments for your scanner in the configuration file. The files are in the directory /etc/sane.d/. They are named after the manufacturer.
For instance, in case of a Mustek scanner the file would be named /etc/sane.d/mustek.conf. Depending on the connection type or device configuration, the line could look like this:
/dev/sg4 # /dev/scanner
Please delete the comment beginning with a # after the device file. The file should now look like this:
/dev/sg4
Please do not simply enter /dev/sg4, but leave the displayed file name as it is.
