The warning message should probably be suppressed for ethernet interfaces, though many modems provide an ethernet interface too.
I also see it for this:

I ran into this on ppc64 F21 Alpha, on a G5 mac (USB only, no discrete serial ports). ModemManager appeared to start to loop, preventing completion of the boot process. This is ModemManager-1.4.0-1.fc21, same as F21 primary.
I opened https://bugzilla.redhat.com/show_bug.cgi?id=1151853, and proposed it
as a F21 ppc64 alpha blocker. Dan Horák moved it to ppc64 GA blocker list.
The S390 Rawhide compose started at Mon Oct 27 08:10:03 UTC 2014 had the following update.
- Initially I thought that it sounded like a good candidate to cherry-pick for
F21 PPC final (or beta, depending on timing and whether primary arch will
accept this as a freeze exemption).
- I just noticed that it is actually a lower version than on F21. If F21 has
a higher NVR, it seems like 1.3.0 and 1.4.0 still have issues with USB modem
device recognition. Any thoughts?
* Tue Aug 05 2014 Dan Williams <firstname.lastname@example.org> - 1.3.0-1
- Update to git development snapshot
- Add IPv6 support for many devices
- Updated blacklist for non-modem USB devices
- Support for more MBIM devices from various manufacturers
- Support for more Huawei devices with network ports
- Add new "unmanaged" GPS location mode
- Many bug fixes for various modems
This bug appears to have been reported against 'rawhide' during the Fedora 22 development cycle.
Changing version to '22'.

Hello! I am still getting these messages after upgrading to 1.4.14-1.fc23.
Specifically, for the two interfaces I have, a Belkin N600 dual band USB modem
and what appears to be the on-board ethernet adapter:
