What I meant was the log output when the scanbd daemon starts via the 
upstart service or the start-script.

But you can start the scanbd in foreground:

scanbd -f

Then wait a few seconds until it figures out what devices are connected. 
You should see something similar to (don't worry about the privileges at 
the moment):
