[sane-devel] Canoscan LiDE 25 detected by find-scanner,

Thank you very much for your reply. I remember originally the dev
files for libusb were not installed on Ubuntu. This meant that
sane-find-scanner didn't find any devices. I realised this was the
problem, installed the dev files, redid the ./configure and forced it
to re-make everything. This is where I was at when I got the output
in my original email.

I'm afraid I'm still pretty new to linux so I'm not sure how to answer
this definitively. I do know that USB pen drives and such work fine on
the machine and when I do 'lsusb' with the Canoscan attached it is
listed as an attached device.
The output of 'sane-config --libs' is as follows:
-lsane -lusb -lpthread -lm -ldl
So I seem to be missing
-ljpeg -lieee1284 -lgphoto2 -lgphoto2_port and -lresmgr
Do you think this is the cause of the problem? If so am I right in
guessing that I need to find and install some more dev files and re-do
the ./configure & make?
