Hi, Can someone help me to solve the problem below?
I have usrp1 with RFX1800. When running usrp_fft.py I get error "failed to set initial frequency" and see no spectrum. starting usrp_fft.py -R A helps at the beginning, I can see the spectrum, but any attempt to change the frequency freezes the spectrum or causes it to dissapear and says "failed". And as you can see there are some fusb, libusb errors.
My usrp was working fine untill I upgraded to ubuntu 12.04 and reinstalled gnuradio.
robert-pc:~/gnuradio$ usrp_fft.py
fusb::_reap libusb_handle_events() -10
(python:26722): LIBDBUSMENU-GLIB-WARNING **: Trying to remove a child that doesn't believe we're it's parent.

I installed dependecies with build gnuradio script, then I did manual installation. I have Ubuntu 12.04 3.2.0-55-generic-pae i386 i686.
I configured gnuradio with the following command:
PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/ ./configure -q --prefix=/home/robert/gr342 --disable-gr-qtgui --with-fusb-tech=libusb1 --enable-usrp --enable-gr-usrp --enable-gnuradio-core --disable-usrp2 --disable-volk
my .bashrc is below, I have a symbolic link pointing .sys > /home/robert/gr342
PREFIX=/home/robert/.sys
export PATH=$PATH:$PREFIX/bin:/opt/microblaze/bin
export LD_LOAD_LIBRARY=$PREFIX/lib
export LD_LIBRARY_PATH=$PREFIX/lib
