[sane-devel] how do you use "saned -d and -s?

[ToddAndMargo]

Dear list,

Scientific Linux 7.4 (RHEL Clone based on CentOS)

# rpm -qa sane-backends
sane-backends-1.0.24-9.el7.x86_64

# ps ax | grep [s]aned
29857 ? Ss 0:00 /usr/sbin/saned -a saned -d128


How do I use
/usr/sbin/saned -a saned -d128
or -s
to see why a scanner command is crashing?

Simple Scan works.

PDF Studio requires saned be running and does find the scanner,
gives me the following error:

com.qoppa.uk.b.b.e.m: Invalid operation

Many thanks,

-d handles only one connection, and then exits. Maybe PDF studio needs to
connect twice. If this is your case, you simply cannot use -d/-s. -s is
just the same but redirects output to syslog.

The next release will change this behavior to something similar to what -d
generally mean in other commands (without quitting after the first
connection).
