Usrp permission rights on ubuntu 12.04


I would like to ask whether there are some changes in ubuntu 12.04 for
usrp permission rights. After upgrade to 12.04 i can’t run
gnuradio-3.4.2 scripts/programs (like usrp_fft, lsusrp) without root
permission (with root permission it works fine). The udev rule is on
right place (this one: ACTION==“add”, BUS==“usb”,
SYSFS{idVendor}==“fffe”, SYSFS{idProduct}==“0002”, GROUP:=“usrp”,
MODE:=“0660”), i’m also member of usrp group, however usrp device isn’t
visible as usrp on /dev/bus/usb

does someone know what the problem is?


p.s. ubuntu 12.04 needs addition libaudio-dev package for gnu-radio
