I have a usrp1 and want to execute usrp_wfm_rcv.py using TVRX
daughterboard. ( Also tried to send a signal with gnuradio-companion.
(Usrp-source + scope-sink) ) But an error occured : UHD error :

After this tried RFx1800 daughterboard with gnuradio-companion, then
it
worked. So usrp1 is seen by my computer. (no problem )
But TVRX board didn’t worked !!!
