I have been using the Mac Pro for about a year now and am having an issue with my Epson Perfection scanner not working all of a sudden... worked fine for months and now its like Mac can't find it even though it shows up in applications. I've reloaded the drivers, changed all the cables but nothing worked. Scanner works fine on the Windows XP PC but not the Mac where I work in Photoshop all day. Any help would be appreciated!
