The binary installation on Ubuntu creates a user group 'usrp', and sets the permissions for USRP access via USB to allow any user who is a member of that group. The final part of the install instructions tell you to add your user account name to group 'usrp' and then log out and back in as that user for it to take effect. This is why running as root via sudo got past this part. > Can't find fpga bitstream: std_2rxhb_2tx.rbf This should have been installed into: /usr/share/usrp/rev4/std_2rxhb_2tx.rbf First verify if it is there; if it is not, then the 'usrp-firmware' package didn't get installed for some reason. You can do 'apt-get install usrp-firmware'. > FYI: This is on a Dell netbook (Inspiron 910) and apparently you can't > actually log in as root. Ubuntu, by default, disables the root account login, and allows the user configured during installation to use sudo instead.
