Dear all,

I am trying to connect over PCIe to my USRP X310. I have installed the
latest drivers niusrprio-installer-18.0.0.tar.gz and I am starting the PCIe
connection with the following command:

sudo /usr/local/bin/niusrprio_pcie start
Making sure drivers are up to date...
Module nikal is up-to-date
Module nibds is up-to-date
Module nistreamk is up-to-date
Module NiRioSrv is up-to-date
Module niusrpriok is up-to-date
Loading: NiRioSrv niusrpriok
Starting: niusrpriorpc

Then I try the uhd_usrp_probe:

uhd_usrp_probe --args "type=x300,resource=RIO0"
[INFO] [UHD] linux; GNU C++ version 5.4.0 20160609; Boost_105800;

I have another PC and USRP x310 and this is working fine. I have followed
the exact same steps and there isn't any issue. What could be the problem
and how can I debug this further?

Regards,
Akın
