This is not a development question. I have tried everything to figure out what the setup for using the umax_pp backend might be. When I was using the old umax_pp driver under RH7.1, I set an environment variable (SANE_DEFAULT_DEV, I think) to umax_pp:0x278 (or similar). I had to be root then when using scanimage. I have looked through the man pages and they are not particularly helpful. Does anyone have an example of how to set up the backend for use with an HP3200C scanner?
Thanks in advance.
