Does your scanner show up in the output of `scanimage -L`?

If not, it could be that scanimage is not loading the driver, perhaps 
because it cannot find the library.

Running `strace scanimage -L 2>&1 |grep ".so"` should give you some output 
that shows which shared libraries it tries to load and where it tries to 
load them from.




Best wishes,
@ndy
