Greetings to the group This is another connection issue for the B210, however I think it somewhat unique having tried the solutions provided for other users, although I am a newbie so it could be something very obvious or I misunderstood previous instructions. I am using --
Ubuntu 14.04 (VM VirtualBox) GNURadio 3.7.3 UHD 003.007.001 (which I understand are the latest versions, from the repository and have tried both stable and unstable versions). >From a clean snapshot (without any GNU radio, python or UHD) and following >advice from the forums I performed the following installation sequence -- sudo apt-get install python python-wxgtk2.8 pyqt4-dev-tools python-qwt5-qt4 python-numpy libboost-all-dev libusb-1.0.0-dev sudo bash -c 'echo "deb http://files.ettus.com/binaries/uhd_stable/repo/uhd/ubuntu/`lsb_release -cs` `lsb_release -cs` main" > /etc/apt/sources.list.d/ettus.list' sudo bash -c 'echo "deb http://files.ettus.com/binaries/uhd_stable/repo/gnuradio/ubuntu/`lsb_release -cs` `lsb_release -cs` main" >> /etc/apt/sources.list.d/ettus.list' sudo apt-get update sudo apt-get install -t `lsb_release -cs` uhd gnuradio sudo apt-get install python-cheetah I get the report in gnuradio that the device cannot be found (I have tried running both as sudo or as a normal user in case of permissions -- a bit new to linux). When setup with just a UHD source and a FFT sink GNURadio returns: RuntimeError: LookupError: KeyError: No devices found for -----> Empty Device Address Seeing the solution provided in this mailing list I have tried to modify udev rules as follows: sudo gedit /lib/udev/rules.d/40-uhd-host.rules SUBSYSTEMS=="usb", ATTRS{idVendor}=="2500", ATTRS{idProduct}=="0020", GROUP:="usrp", MODE:="0660"I have also tried with the stable equivalent, again from a fresh snapshot. When I run lsusb I can see the device 2500:0020 (sometimes) although it frequently disappears. Bus 001 Device 032: ID 2500:0020 Bus 001 Device 007: ID 80ee:0021 VirtualBox USB Tablet Bus 001 Device 006: ID 0bda:0129 Realtek Semiconductor Corp.

BCM43142 Bluetooth 4.0 Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Using sudo uhd_find_devices I get the following, which appears like it has identified something as it tries to load image (unlike it not connected) but then fails: linux; GNU C++ version 4.8.2; Boost_105400; UHD_003.007.001-20-unstable -- Loading firmware image: /usr/share/uhd/images/usrp_b200_fw.hex... done No UHD Devices Found I am not sure why it is trying to load b200 when it is a b210 (4 ch)? I read that using uhd_usrp_probe with an address might work but unsure how to do this without an IP address. I have tried both powering through the USB only or providing 6V in case it is a supply issue, noting in the second case a change in current draw once I start trying to interact from 40 mA to 120 mA. Many thanks for any pointers -- Steve
