I have a great number of slides slowly decaying in their storage area. I guess I could put'em on a flat-bed and take my chances, but since I don't have a scanner now, maybe I shouook into buying a slide-scanner.
Are these things generally like a regular scanner in terms of installation, or do they use funky USB mechanisms? Anyone have experience with something like this?
I have a Minolta Dimage V and use vuescan. It works like a charm with only a few problems.
- couldn't get it to work under Linux with USB 1.1. The scanner would lock up. XP handled the USB 1.1 connection just fine. My desktop system has USB 2 and the problems went away. - whenever I scan to a tiff file, the file loads up into Gimp. I haven't figured out how to get it to scan to a disk file yet. - vuescan needs to be run as root. This is new with my installation of FC3; under the TEST versions, my normal user account could access the scanner. I've tried a mod to the usbscanner script to set the permissions to allow non-root users to access the scanner, but I don't have the answer yet.

I don't know if this is your problem or not, but ...
There is an unresolved bug that incorrectly sets the permissions on usb scanners. One way to make it work as a user is to unplug/plug in the usb cable to the scanner after boot. This is a PITA and probably is not good for the connector in the long run. The alternative is to write a script that changes the permissions.
First, you need to identify the file with scanimage -L or sane-find scanner run as root.
In my case, [root@gstpc-fc3 acroread]# scanimage -L device `epson:libusb:003:002' is a Epson Perfection1240 flatbed scanner
Then create a script; in my case I have /usr/local/bin/fixscan which has a single line
chmod a+w /proc/bus/usb/003/002
I run fixscan as root after reboot and the scanner is then usable by my normal user account.
Hope this is useful.
