Hello,I did find a simlar entry to this problem on the forum from last month but there was no usable solution for me unless I missed something. Also I have not found a way to allow me to change the USB permissions. Any advise will be a great help.ThanksJohnI have this issue on TWO DIFFERENT MACHINES. Here is what I did on each of them:Completely fresh install of Ubuntu 12.04.4 LTSapt-get updateapt-get upgradeapt-get libasound2-dev (because I need to use an 8 channel USB sound card with my GRC app)install and configure pybombs (used all default settings)./pybombs install gnuradioeach time I want to run gnuradio-companion I must first set the enviroment (a minor annoyance)./pybombs env
source /home/xxxx/target/setup_env.sh
sudo /home/xxxx/target/lib/uhd/utils/uhd_images_downloader.py
and thengnuradio_companion (GRC 3.7.5 GUI works fine)However, I have no connection to the USRP B200uhd_find_devices or uhd_usrp_probe returns the following:UHD Error:USB open failed: insufficient permisssions.See the application notes for your device.No UHD Devices Foundrunning lsusb returns the following:Bus 002 Device 006: ID 2500:0200according the information in ~/target/lib/uhd/utils/uhd_usrp.rules, ID 2500:0200 is the B200 USRP
