Your driver setup may be a factor. The 'lsmod' command will list what drivers are loaded.  Be sure the Ethernet driver you have is Gig capable.  For my system it is an e1000e for Intel. Reloading the driver may help "clean up" the connection. Run modprobe -r driver name followed by modprobe driver name. Also, ensure that the Ethernet connection is configured for Gig. The command ethtool eth0 (provide correct designator for you system) should list the current configuration for you system. Finally, be sure that the ifconfig for the eth0 (provide correct designator for you system) is set up to communicate on the network... is recommended as the host ip address. If this is all sound, consider running Wireshark to monitor the connection activity between the host and USRP. You may see an ARP when the USRP comes on line and you should see the communication between the host and the USRP. Then there is always the host and USRP reboot.

Walking through these steps has helped re-establish connectivity for my system when No UHD devices found or Discovered device ignored is returned by the uhd_find_devices utility.

 I can't connect to the USRP2 using the latest version of the UHD driver from the git repository. I am using Ubuntu 10.04 and I have followed the instruction at http://www.ruby-forum.com/topic/213259 but still when I connect usrp2 to computer and check the output
linux; GNU C++ version 4.4.3; Boost_104000; UHD_003.000.001-e2cd276
No UHD Devices Found
can anyone help me with this.
