Communication Error using USRP with XCVR2450 Daughter-boards

GNU Radio

Hi All,
I am trying to communicate between two USRPs with XCVR2450
daughter-boards attached with two separate PCs. When I tried running
benchmark_tx.py, an error appeared;
“ValueError: No class defined to handle daughter-board (dbid = 96)”

Can any one please help me rectify the error. Waiting reply.

Which Gnuradio trunk do you use？

Unfortunately，gnuradio 3.1.3 does not support XCVR2450 daughterboard.
You should install the lateset trunk by svn.

I downloaded the latest code from trunk using:
$ svn co http://gnuradio.org/svn/gnuradio/trunk gnuradio

But, still the error is same, with changed dbid.
“ValueError: No class defined to handle daughter-board (dbid = 97)”

Do I need to modify anything else as well?
