[Discuss-gnuradio] Unknown dboard-id

[Ninja]

I tested the usrp2 using uhd_usrp_probe, why is there a warning about unknown 
dboard-id or dboard-id combination and Unknown value for RX Subdev and TX 
Subdev (antenna?)?is there some miss when I assembled the device?or it's needed 
to configure through software?
