Dear all,

I've reinstalled gnuradio 3.7.0 and UHD 003.007.001. Now I got this
when connecting USRP to my PC and running some commands:

1. sudo uhd_usrp_probe
linux; GNU C++ version 4.6.3; Boost_104601; UHD_003.007.001-release

Error: Connection refused

2. sudo uhd_find_devices
linux; GNU C++ version 4.6.3; Boost_104601; UHD_003.007.001-release

UHD Error:
    Device discovery error: Connection refused
-- UHD Device 0
Device Address:
    type: usrp1
    serial: 50a45bfc

How could I fix this?

Many Thanks,

The 'connection refused' error is probably due to your firewall
configuration blocking network broadcast probes which are sent for
detection of ethernet connected USRPs. Try the following to force it to
connect to the USRP1 type:

uhd_usrp_probe --args="type=usrp1"
