I use multiple NICs on my laptop all the time. I have the onboard NIC and
up to three additional USB NICs and as of yet have not experienced this
issue. Each NIC gets a new name in NetworkManager for me. I have labled
my USB NICs with the last 2 of their MAC so I can easily identify them. I
am running Ubuntu, so there should be little difference from my experience
to yours.
If you make any reference to an interface in /etc/network/interfaces,
NetworkManager then will exclude that device from any management so you
don't have an issue with management overlap.
