Well, I've tried this path on actual 1.7.3 (where the code is moved some 12 
lines - beginning with 2700).
!! - no output "skipping device"! Also when starting main processes and 
-bind-to-socket used. What I see is

[cluster.rz.RWTH-Aachen.DE:43670] btl:usnic: found: device mlx4_1, port 1

[cluster.rz.RWTH-Aachen.DE:43670] btl:usnic: this is not a usnic-capable device


That's actually ok -- that's from the usnic BTL, not the openib BTL.

The usnic BTL is the Cisco UD verbs component, and it only works with Cisco UCS 
servers and VICs; it will not work with generic IB cards.  Hence, these 
messages are telling you that the usnic BTL is disqualifying itself because the 
ibv devices it found are not Cisco UCS VICs.



Argh - what a shame not to see "btl:usnic"  :-|




Look for the openib messages, not the usnic messages.


Well, as said there were *no messages* form the patch you provided in
http://www.open-mpi.org/community/lists/devel/2013/06/12472.php
I've attached of a run with single process per node on nodes with 2 NICs, maybe you can see what goes wrong.. 

Best
