Fell free to mark this as fixed.
The problem is that the closed source driver software by samsung looks
for the usb device on
/proc/bus/usb/00*/00*
and AFAIK 8.04 drops support to /proc/bus/usb/00*/00* and port all
software to see the usb devices only on /dev/bus/usb/00*/00*
To reenable support on /proc/bus/usb I edited
/etc/init.d/mountdevsubfs.sh
and I modified the lines
#
# Magic to make /proc/bus/usb work
#
#mkdir -p /dev/bus/usb/.usbfs
#domount usbfs "" /dev/bus/usb/.usbfs -obusmode=0700,devmode=0600,listmode=0644
#ln -s .usbfs/devices /dev/bus/usb/devices
#mount --rbind /dev/bus/usb /proc/bus/usb
to
#
# Magic to make /proc/bus/usb work
#
mkdir -p /dev/bus/usb/.usbfs
domount usbfs "" /dev/bus/usb/.usbfs -obusmode=0700,devmode=0600,listmode=0644
ln -s .usbfs/devices /dev/bus/usb/devices
mount --rbind /dev/bus/usb /proc/bus/usb
and reboot. After that, the scanner works like a charm on Hardy Heron.
