Just to rule out a problem, are you trying to run both Tx and Rx
concurrently using a single USRP1 connected to a single computer?  
If so, you need to specify the same .rbf file for both the Tx and Rx
sides, otherwise the last one opened stomps on the first one opened
when it reloads the FPGA with the "other" .rbf image.
