Re: [Discuss-gnuradio] "uhd_find_devices" command returns "No, UHD Devices Found"

[Nakajo Tomoyuki]

I use UBUNTU 10.10.
I configured eth0 for a static address 192.168.10.2. by setting "Network 
connections" in "System->Preferences". Connection is enabled, however, 
"uhd_find_devices" cannot find any devices.

The result of 'sudo ./uhd_usrp_probe --args "addr=192.168.10.2"' is below.

----------------------------------------------------------------------------------------------

Is perhaps Network Manager taking your ethernet interface down?   It
needs to be configured
  for a static address assignment with no DHCP.

Also, what happens when you:

uhd_usrp_probe --args "addr=192.168.10.2"
