Looking at the umax backend, I think the problem is line 7993 in umax.c that says: if (scanner->reader_pid < 0) This line should be if (scanner->reader_pid = -1) I have compiled a test package where I have applied this change, which is available here: http://www.ellert.se/PKGS/test/sane-backends.pkg.tar.gz Let us know if it works for you.
