- sane-find-scanner only checks libusb can detect the scanner, not if SANE's backends are working or not. So all is well on that front at least. - check if pixma_mp150.c has this scanner listed in it. At the tip f the file the USB ID, at the bottom of the file the properties. - check if you compiled correctly (local compiles by default go into /usr local so your scanimage should be running from there) - run scanimage as root to see if it might be a permissions issue HTH as a start, Gernot Hassenpflug
