  # No SCSI scanners found. If you expected something different, make sure that
  # you have loaded a kernel SCSI driver for your SCSI adapter.

=== Solution

Source https://forum.ubuntu-fr.org/viewtopic.php?id=1080701

<code bash>
wget https://bugs.archlinux.org/task/20374\?getfile\=5563 -O  cism216.fw
mkdir /usr/share/sane/gt68xx/
cp cism216.fw /usr/share/sane/gt68xx/
chmod -R a=rwX /usr/share/sane/gt68xx
</code>

<code bash>
cp -p /etc/sane.d/gt68xx.conf{,.orig}
vim /etc/sane.d/gt68xx.conf
</code>

Il faut ajouter les lignes suivantes :
<code ->
override "plustek-opticslim-1200"
firmware "/usr/share/sane/gt68xx/cism216.fw"
</code>

Ça doit ressembler à 
<code - /etc/sane.d/gt68xx.conf>
