You can do that, but if you have a lot happening in /var/log/messages 
and it's pretty busy then running the "dmesg" command after inserting 
the USB drive, it displays the kernel message buffer, so would be 
limited to the loading of drivers etc... the end of the output should 
correspond to the device you just connected.
