Re: [Discuss-gnuradio] Problem with USRP B200

[Balthasar Indermuehle]

in my USRP source blocks I use the serial numbers of my devices (I
usually have two connected simultaneously) in the device arguments
string. Simply set the device argument string to "serial=yourserial"

Works all the time everytime, on OSX, and several different Linux distros.
