All,

When I connect my USRP N200 to a PC running Suse, run ifconfig eth0 192.168.10.1 command, and then run command uhd_usrp_probe --args="addr=192.168.10.2", I see the famous error message:

LookupError: KeyError: No devices found for ----->
Empty Device Address

The weird fact is that I have 9 other USRP N200 radios which get detected when I run the command uhd_usrp_probe --args="addr=192.168.10.2" on the same PC (so it shouldn't be a firewall issue). For the problematic USRP N200 I have done the following:

ping 192.168.10.1 which is fine

ping 192.168.10.2 which shows the error message that destination is unreachable

I have also used switch S2 to enter into safe mode, burn the right binaries (3.4.4 from maint branch), power-cycle the device but the problem persists.

Any ideas on what might be preventing the USRP N200 from being identified by the host PC?

Does the green "Link" light on the USRP come on, and does the yellow activity light blink from time to time when
 it's plugged in to the host machine?
