I've got an Epson Perfection 2450 photo scanner. I've been using it with my computer which is running FC3. It used to work beautifully, apart from the slight quirk that I would have to start xsane, shut it down then start it again (second time takes much longer) to get it to work. A few days ago after some updates I think, it stopped working. Tried it on my son's computer yesterday, which is running FC4, but hadn't been updated for some time, and it worked. Great. Updated his computer yesterday evening, tried to use the scanner just now, it won't work on his computer either now. Not great. Now I can't scan at all. The error message when I try to start preview is "Failed to start scanner:- Error during device I/O" Has anybody else had this trouble or much better know how to fix it? I did try google with the error message. Somebody thinks it might be to do with libusb.
