Essayez peut-être en utilisant ce fichier de config :
# Plustek-PP SANE Backend configuration file
# For use with Plustek parallel-port scanners
#
#
# user either [direct] or [kernel] to access the scanner
# when using [kernel], device specifies the device-node, which is created
# by the kernel-module loader (applies only to Linux)
# when using [direct], device is used to set the parallel-port base address
# or a device-name suitable for libieee1284, i.e. parport0
#
[direct]
device 0x378
#
# example for accessing the scanner via libieee1284
#
#[direct]
#device parport0
#
# leave the default values as specified in /etc/modules.conf
#
option warmup -1
option lOffOnEnd -1
option lampOff -1
# model override switch, mostly for cosmetic changes, if the autodetection
# does not work or could not work correctly
option mov 6
#
# example for accessing the scanner via the kernel module
#
#[kernel]
#device /dev/pt_drv
#
#option warmup -1
#option lOffOnEnd -1
#option lampOff -1
Si ça ne fonctionne pas, il faudrait essayer en compilant le module comme l'expliquait gigiair dans un message précédent.
