Look at your system log files: /var/log/messages
Look around the time of your system boot up, and look for USB messages
and networking messages, particularly anything with "eth" in it.
Any/all could help you track down what's wrong
Can you see your ethernet card with "lspci"?
What does "ifconfig -a" tell you?
Has your /etc/modprobe.conf been modified recently?
Do you have the appropriate modules loaded? "lsmod"

I don;t know what pan0 is (google for it), but if you hardware has
changed names, that could very well be your problem. The solution would
be "how do I fix it?".
