When you install UHD from our binaries, it's important that you first uninstall
your Linux distro's UHD and GNU Radio and you _must not_ re-install GNU Radio
from your distro's package manager but build it from source, otherwise, you
will get library incompatibilities and segfaults.
But that is a separate issue from uhd_usrp_probe not finding devices. Make sure
the USRP is connected and powered up _before_ you boot your PC, then verify you
can see the device via pcie and that the nirio module is loaded [1].
I hope this helps,
Marcus
