I must apologize, I should have said "type=x300".

But your subsequent uhd_usrp_probe output (note, that sudo should not be required for any of this) shows that the version of UHD you have recognizes
  the card

My guess is that your srsLTE environment is linked against a different, older, version of UHD which doesn't have TwinRX support. Note also that a full
  LTE stack will not work with a receive-only card like the TwinRX.



I am not pretty sure that the command is correct. So, I am going to show you the output of sudo uhd_usrp_probe too:

        Dear Marcus,

        Thanks for the response. The UHD version is
        UHD_003.010.002.000-release.

        So, this version is the correct one?

        Best regards,
        Alejandro

    Could you show us the output of:

    uhd_usrp_probe --args "type=x310"
