Content-Type: text/plain; charset="us-ascii"
Hi folks
After a long struggle with installing and configuring USRP N210 I am getting a
warning that I have no idea how to fix and don't know if it is important enough
to spend time on it. I really appreciate your help to fix this last remaining
issue I have with my environment.
this is the result of the uhd_usrp_probe when I run it:

Hi Farhad,
I also got the same warning with USRP2. Try "sudo uhd_usrp_probe".
It worked for me.

Hi Josh,
Got it to work. I still have this annoying problem that I need to set the eth0
to the correct address after each re-start of the computer.
This has been an extremely unpleasant and annoying experience. I have never
paid
so much money for a piece of hardware that comes with absolute no
documentation,
old FW and FPGA code. If it wasn't for the help of people on this list, I would
have never managed to get this working.
I have bought products far cheaper than this from someones garage shop on e-bay
with better documentation than USRP. And they work right away and I don't need
to spend hours searching for proper documentation, recompile the whole damn
thing before I can just run a simple test. This is just pathetic.
/Farhad
