Was I doing something wrong? The benchmark is meant to be run with the basics daughterboards or it can be run with any daughterboards? I do need to use the RFX1800 for the openBTS testing.
I still got the same odd error. I don't know what's wrong. Now I'm trying to run usrp_probe to check the daughterboards and I got, I believe, the same error.
I have two RFX1800 daughterboards, when I plug them at the same time, none can be recognized by the usrp. I get this:
>>> Error
can't open usrp
If the USRP cannot be found, make sure that the USRP is plugged-in and restart this program. If the problem persists, there may be a problem with you gnuradio installation or USB 2.0.
But if I unplug any of them I can read the results normally:
>>> USRP Probe
Name:
Flex 1800 Rx MIMO B
Converter Rate:
64000000
Uses Quadrature:
True
Gain Range (min, max, step size):

Does anyone have a clue of what could cause this?
Thanks in advance for any answer,
