Is your computer showing the correct time? Is it set up for your time zone? In Orage, you start the program, click on Edit, Preferences, click on the Timezone tab, click on the Timezone box, click on America/New York, click on OK, then click on Close. If you've tried this and it's not working, I have no idea what to do.
Have you run sane-find-scanner as root? It'll tell you the /dev identification of the scanner. As root go to the /dev directory and look for the scanner as identified by sane-find-scanner and change the permissions. I do this with Midnight Commander (Control x. o on the highlighted file) and change the group ownership to scanner. Save your changes. Users in the scanner group should now be able to use xsane.
My computer connected to a scanner is not turned on now, so I'm going by memory. I hope I didn't forget something!
