maybe I'm ignorant, but I could not find a BUG! The backend works okay.
The informations I got from i.e. xsane are correct. The model name
printed on my scanner is: CanoScan N1220U.
scanimage -L reports: 
device `plustek:libusb:003:003' is a Canon N1220U USB flatbed scanner
--> so what?

SANE_TYPE_OPTION does not exist - also I only see 1 button. 
At least that's what I see here. 

Could you be please more specific?
