I reran the command for each individual USRP radio connected.

Two of my USRP N210s have this output:

Error: RX dboard has empty serial!

One of my USRP N210 has this output:
Error: timed out waiting for TX and/or RX LO to lock

and the USRP1:

Error: self-calibration is not supported for this hardware.

I can understand if the self-calibration is not supported for the USRP1.

However, for the USRP N210s I would like these fixed.  I ran uhd_usrp_probe
and it seems like by dboard has a serial.  It says TX Dboard: A ID:

Is there a bug in the calibration routines?
