My bad--dll.conf was missing. I confused the dll.conf file with the
windows type .dll files and should know better :-(

Prints heaps and identifies the scanner at /dev/sg1 and/dev/scanner.

Having found the scanner, running 'scanimage -d umax:/dev/scanner' fails.

The scanner attempts to start up then dies, uninstalling the scanner in the
process.
Here is a partial screendump of the output of the command.

After this the lamp remains on but the scanner has to be repowered and
reinstalled from the command line before scanimage can see it.

Is there any more info I can supply?
