IL n'y as aucun fichier snapscan.conf dans le fichier.
Le programme passe probablement tout les scanneurs inscrits dans le fichier /usr/lib/sane pour ensuite v�rifier leur configuration dans le fichier /etc/sane.d/nom du scanneur pour ensuite faire le tour de la machine pour voir si un tel scanneur est pr�sent.
Il recommence par la suite..... pour un autre scanneur...
Il y-a-t-il un moyen d'�viter cette situation.
Excusez mon interpr�tation mais je ne suis pas un informaticien......
Je vous remercie et je vous laisse un exemple d'un partie du r�sultat de tracesnapscan.

Il recherche explicitement un fichier qui s'appelle /path/to/your/firmware/file.bin
C'est assez cocasse.
Ce qui veut dire que :
- soit vous avez un fichier de config avec cette entr�e
- soit il n'utilise pas le fichier de config et prend une valeur par d�faut cod�e en dur dans le programme.

Ce qu'il faut faire amintenant, c'est remonter encore un peu dans votre fichier trace et de chercher l'endroit o� il va ouvrir le fichier snapscan.conf.
Vous devriez trouver un open("/etc/sane.d/snapscan.conf".... ou open("/usr/share/sane/....
et ensuite il va dire qu'il trouve ou ne trouve pas le fichier en question
Merci encore et d�sol� de prendre de votre temps.
