[sane-devel] sane fails to recognize my nikon coolscan IV

[Travis Parker]

I can't seem to get my nikon coolscan IV film scanner (should be fully
supported by sane-coolscan3) to be be recognized. sane-find-scanner sees
and identifies it, but scanimage -L doesn't, nor does xsane or anything
similar.
                         
I've looked around the archlinux forums, the archives for this list, and
can't find anything that seems to fit my issue.
                         
Any help would be much appreciated!
