I just built a SAN running TrueNAS Core 12, and am seeing a phantom USB ethernet adapter, I would kind of like to either identify or make go away. It's not causing problems really, it's kind of annoying, but it's also the principle of the matter as well at this point :wink: I suspect it's some aspect of the IPMI or other component on my motherboard:

I do also happen to have an actual USB ethernet for now :eek: just used to access the management interface, as I'm out of PCIe links unfortunately. I tried simply "deleting" ue1 however it seems to come back after a reboot, and last time I tried, grabbed the static that was assigned to ue0 (I think 0 and 1 switched) which caused me to have to whip out a nowadays hard to find VGA cable and muck around at the console level for a bit.

The board is this: https://www.asrockrack.com/general/productdetail.asp?Model=C3558D4U-2OP#Specifications
Oddly enough, ifconfig -a does not even show this interface! I see ue0 with all it's stats...
Any advice? I'd be happy if I could just hide this from the dashboard somehow.

EDIT: I may be mistaken? I'm not sure what lo0 corresponds to...
Code:
root@truenas[~]# ifconfig -a

I've no idea what ue0 is, but lo0 is the local loopback virtual adapter, and is a required part of the networking system. You can ignore it :)

/edit just to say I don't have any ueX devices on any of mine.

I had the same thing not that long ago. I just went under the interface tab and deleted it, and it hasnt come back. No issues.
