It was the ethernet card. Just a suggestion but it might be nice to add this to the debugging network problems section of UHD-USRP2 Application Notes. Thank you very much Josh! Specifically I found uhd_find_devices and uhd_usrp_probe --args to be useful next steps after pinging the usrp2s to find

The no control response might mean the pause frames are messing up the control packets. Does this happen in a receive only application? One way to alleviate this would be to run the flow control branch and images. See the flow control branch on the UHD repo. and images are here: http://www.ett
