Are you saying that if you run the same flow graph, host pc, ethernet
port, and software install on the USRP2 + WBX, you do not see this problem?
I am confused about the one hardware not working while the other does,
because its functionally identical. Just wondering if we can isolate
this problem to a particular machine, software install, etc... instead.

This is the call to recv() on the udp socket timing out. Either data
isnt coming over the ethernet cable for some reason recv()/select()
error-ed.
In any case, do you mind trying the next branch?
In the uhd repo:
git remote update
git branch --track next origin/next
git checkout next
cd host/build && make install..
and for gnuradio
git remote add jblum git://gnuradio.org/jblum.git
git remote update
git branch --track gr_uhd_next jblum/gr_uhd_next
git checkout gr_uhd_next
make install...
