This is always useful for reading what dmesg and other things that
dump into syslog are saying as you do something.

If you want to REALLY get crazy, do it like this:

# tail -f /var/log/syslog &

which background the process, but will still dump something to console
whenever dmesg receives a message (or syslog for that matter).

Thus, you can now type commands and find out of anything is generated
in syslog as a result of your commands (like when restarting apache,
or dhcp).

To get out of it, type:

# fg

to bring the process back to the front and then ctrl-c to kill it.

Also, for your usb, have you tried using 'lsusb' after plugging it in
also to see if it appears at all on the USB bus? Granted, if it
doesn't cause USB messages to be generated initially in dmesg, it
probably won't appear in lsusb either, but it's worth checking.
