I am not sure that this will solve the issue, but it is what I'd try:
Usually when a nic is added a new line for that card is put to this file:
/etc/udev/rules.d/70-persistent-net.rules .
you could edit that file and
1- delete the line for the old usb nic [ assuming you are not going to use
it ].
2- change the new nic line to eth1 [ it is probably assigned to be eth2 ]
3- reboot.
Unless you edited /etc/network/interfaces ?
PS: usually I just delete /etc/udev/rules.d/70-persistent-net.rules , and on
reboot it gets recreated. The thing is you never know for sure which of the 2
nics is eth0 or eth1 . But swapping the patch cable fixes that.
