Well that works now.

It seems not: when I launch my homemade scanning script the scanimage
message says:
scanimage: no SANE devices found

Note that I tryed th next:
sudo chown yp:scanner /usr/local/bin/scan2*
(to sete my scripts in the scanner group,
idem I did: chown yp:scanner ~/lin_scans
since taht's my destination dir.

None of any changed something:
ONLY sudo scan2* works.

What am I missing ? (its an USB scanner, so I don't need any /dev/scanner or
so ?
