Hi, I have finally compiled the uhd library. When I do "sudo ./uhd_find_devices" I get "No UHD Devices Found". I have turned off the firewall. I have loaded the firmware unto the SD card. When I turn on the power of the USRP2 first all leds on the front are lit and then only "D" is on.
I know you got me off-list, but I would like to share the answer because people tend to google these things and get list postings:
The solution was to set a static IP address on the network interface. Its not like the raw ethernet communication where sometimes you needed a static ip to make a particular interface work. You always need the static IP address to send and receive the UDP packets.
Also, you should not need the sudo. uhd_find_devices works fine as normal user.
And a little trivia for today: The "F" LED on the USRP2 is actually light (faintly).
