Ah, that... true :-)

Sure, the order matters here. He can re-run the command again to view the 
new messages.

USB (hardware) events are dropped there?

To be sincere, I'm still unsure about what log file holds what 
information. In openSUSE, the main log was "/var/log/messages" and you 
had to look there to see the most relevant information, but here (Debian) 
seems to be "/var/log/syslog". Then there are additional small files for 
authentication, user and other stuff I never remember which is 
disseminated into small registries files.
