the umax-backend hangs in sane-0.67, but here is a patch
that corrects it!
There has changed something in the way the options between
xscanimage (and may be scanimage too) and the umax-backend
were handled and so we got into an endless loop.
At the end of the mail there is a fix for it!
just kill everything until ------------------, save the file
as umax-patch, move it to sane-0.67/backend and then do
cd sane-0.67/backend
patch umax.c <umax-patch
I also had problems to compile the umax-backend because
usleep and strdup were not found any more.
Simple trick at first: use old sane-0.66/backend/Makefile
if you have it!
Bye
Oliver
