normal c'est simplement la marche à suivre pour pouvoir utiliser ton scanner. La partie importante me semble celle-ci :
"FIRMWARE FILE
You need a firmware file for your scanner. That's a small file contain-
ing software that will be uploaded to the scanner's memory. It's usu-
ally named *.usb, e.g. PS1fw.usb. It comes on the installation CD
that was provided by the manufacturer, but it may be packaged together
with the installation program in an .exe file. For Mustek scanners, the
file can be downloaded from the gt68xx backend homepage. For other
scanners, check the CD for .usb files. If you only find *.cab files,
try cabextract to unpack. If everything else fails, you must install
the Windows driver and get the firmware from there (usually in the win-
dows/system or system32 directories). Put that firmware file into
/usr/local/share/sane/gt68xx/. Make sure that it's readable by every-
one."
