After a lot more wrong turnings and much agonising, thinking instead of 
panicking (at last!) and retrying:

root@Eros:/home/lisi/Sane-Files# scanimage -L
device `genesys:libusb:001:003' is a Canon LiDE 220 flatbed scanner
root@Eros:/home/lisi/Sane-Files#  

Thank you so much Brian and didier, especially for your patience.
