Re: UNSUPPORTED error on sane_open?????

Sorry if this is a stupid question, but I am new to SANE. 

How do I crank up the debug level at the command line? I am
accessing the backend through a dynamically loaded library.

I am accessing the backend through a dynamically loaded
library.

at the command line:

SANE_DEBUG_DLL=255 yourprogramname --yourprogramargs

all on one line, will put the DLL backend debug info on
stderr. you
can do the same for the test backend with
SANE_DEBUG_TEST=255
instead/in addition.
