You may want to use ethtool to check the status of the NIC. It
sounds like the link detect is not working. I can not remember off
hand how to disable link-detect, but I know there used to be a way
to turn it off. (The system will not longer try to detect if the NIC
is connected...)

It is possible that the USB problem sent a spike to other parts of
the motherboard when you shorted it out.
