When you have more than one USRP device connected to your system, you really should be explicit about which device you want to address, using the "--args" option.
For your N210 it would be "--args addr=192.168.X.Y" and for your USRP1 it would be "type=usrp1" Otherwise, it just grabs the first USRP device it finds.
