[sane-devel] Canon Pixma MP230

[Marc Marí]

The root problem is solved. I didn't put the scanner on udev rules.

So now, how should I proceed to insert this scanner in sane scanner
database? What tests should I perform, how should I add it to the global
scanner list, etc. I'd like to contribute with this very small patch.
