No, I don't think I ever used USB on this machine. I did some more
tests based on what you said and have the following data points:
- Having a USB device (USB stick) plugged in when booting doesn't
make a difference.
- When I load the de2104x driver _before_ uhci_hcd, both USB and
Ethernet work fine.
- Both modules load fine. USB also works. The problem only occurs
when I actually try to use the Ethernet device (i.e. run DHCP).
Then I get that traceback, and USB also stops working.
