Right now, iscan is installed (used rpm -ivh iscan-...rpm), scanimage -L 
device `epson:libusb:005:006' is a Epson CX7400 flatbed scanner
I unplugged it from the outlet overnight and tried just now - it's still 
working and still showing up as "epson:libusb..."

I'm currently on Fedora Core 6. I used "yum remove iscan" to uninstall 
the package. I didn't check in /usr/lib/sane, but there was an 
epkowa.conf.rpmsave in /etc/sane.d/ after the uninstall. Removing 
.rpmsave file didn't seem to affect anything.
