Michael, Thanks for your answer. My interface is completely 'up' after both commands (promisc up and -promisc). But host computer and USRP2 can only communicate when my network is in promiscuous mode.
I connect both, host computer and USRP2 through a direct connection with a 1 Gb ethernet wire (no switches) I only have one Ethernet interface in my host computer (eth0) and permissions con /usr/bin/usrp2_socket_opener are set to 4775. I still cannot figure out what the problem is.
