If you download the attachment here: 
http://lists.alioth.debian.org/pipermail/sane-devel/attachments/20130327/d616faed/attachment-0001.bin,
...then rename the file to cs3200f.tar.gz you should find that it 
contains the source you are looking for.

I will have a look at it later in the day but in the meantime you should 
be able to check it out.

Cheers,
Ralph
