Since your original post mentions the plan to use a USB<>Ethernet NIC
adapter... I'm presuming you have the USB host port available (I don't
think the client/power port has OTG capability to drive any such adapter)
... Just leave the existing USB network alone -- that's an RNDIS style USB
gadget. The USB<>Ethernet NIC should have its own driver and probably
appears as a different ETH# device. Likely it will even attempt DHCP
negotiation when connected to a live network.
I'd probably just connect that USB<>Ethernet NIC, hook to a local
router/switch, and see what shows up on the network. If the BBB shows up on
the router, SSH to the assigned IP and check the network names and
configuration for it.
Just tried an experiment with an old SIIG USB<>Ethernet NIC. Connected
to a regular BBB, moved my CAT-5 from the on-board Ethernet port to the
SIIG, and booted.

Board has network connectivity over the SIIG unit (USB0 is showing only
since that is how I powered the BBB). Removing the SIIG and plugging into
the on-board Ethernet (and waiting while PuTTY times out a few times)
