DE is icewm, libsane-extras installed, lsusb detects scanner.
For years I have used this scanner by running it from a terminal with
scanimage saving the image in /tmp/image.pnm and transferring it to
gimp to process. I'm sure originally it ran directly from gimp but then
somehow with a new release of gimp the connection was lost. Last week I
got tired of this roundabout method and tried to reestablish gimp's
ability to acquire images directly from the scanner. As yet I have had
no luck with this - hence this posting.
