[Discuss-gnuradio] new modulation schemes do not work on my usrps while the old ones work

hi, I have the latest gnuradio installed on my Ubuntu 10.04 computers and two USRPs with RFX-2400 cards. I tested the benchmark_tx.py/benchmark_rx.py and benchmark_tx2.py/benchmark_rx2.py with dbpsk and dbpsk2 modulation schemes but only the old schemes work.
1. With old schemes both usrps transmit and receive when tested in both tx/rx modes. 2. With the new scheme one of the receive computer displays 'false ' for almost all the packets received. I didn't see any successfully received packets.
3. One of the USRPs in the receive mode doesn't even acknowledge a transmission and hence the benchmark_rx2.py script doesn't print any thing on stdout.
What changes in parameters should I try in order for them to work?
