I've taken charge of my first scanner (a freebie from a friend) but I'm having trouble getting it installed. If I go to XSane it says "failed to open device snapscan :libusb:001:002 " . I have since installed every XSane extra there was via synaptic but it's still won't play ball. I'm very reluctant to give in though so how do I investigate what's up? And even more to the point, how do I fix it? It knows it's there I'm sure.

At a guess, and this will be a guess, the scanner 'device' is owned by the wrong group, or a group you're not in...
do: ls -la /dev/bus/usb/001/002
You should then know what user and group owns the scanner, you can check your own groups using id, if you're not in the group that owns the scanner (I'd guess it'll be "scanner"), then add yourself to the group, logout and log back in again.
All being well, Bob should be your mother's brother.
