Well, I installed a similar setup several times with Kubuntu 12.04, without problems. All the libusb stuff is in place? Anyway, my actual installation is a bad example, two much stuff mixed up, so for example I have no idea what libusb version GR 3.4.2 is using, 0 or 1.

Schmid, dk5ras Cc: discuss-gnuradio@gnu.org Subject: Aw: RE: [Discuss-gnuradio] libusb error with gnuradio v3.4.2git You are right, my intention is to use it with OpenBTS or rather with OsmoBTS. BTS says something like "failed to tune RX ...." and transceiver is not working properly. I also installed gnuradio many times and never had a problem with usrp_fft.py and I completly don't know what the problem could be this time. Looks like the usb transfer is working, but every attempt to change the settings of rfx1800 or usrp fails. The same board works fine on another computer. Gesendet: Donnerstag, 07.

Sounds a bit like OpenBTS to me. If this is your aim, what does OpenBTS say? I never tested the installation this way, just fired the stuff up, and usually it worked :) Ralph.

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. usrp_benchmark_usb.py returns: Testing 2MB/sec... usb_throughput = 2M ntotal = 1000000 nright = 999994 runlength = 999994 delta = 6 OK Testing 4MB/sec... fusb::_cancel_lutusb_throughput = 4M ntotal = 2000000 nright = 1997869 runlength = 1997655 delta = 2345 OK Testing 8MB/sec... fusb::_cancel_lutusb_throughput = 8M ntotal = 4000000 nright = 3998087 runlength = 3998087 delta = 1913 OK Testing 16MB/sec... fusb::_cancel_lutfusb::_cancel_lutfusb::_cancel_lutusb_throughput = 16M ntotal = 8000000 nright = 7999035 runlength = 7999035 delta = 965 OK Testing 32MB/sec... fusb::_cancel_lutfusb::_cancel_lutfusb::_cancel_lutusb_throughput = 32M ntotal = 16000000 nright = 15999605 runlength = 15999605 delta = 395 OK Max USB/USRP throughput = 32MB/sec 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 export PYTHONPATH=$PREFIX/lib/python2.7/site-packages export PKG_CONFIG_PATH=$PREFIX/lib/pkgconfig export PATH=/opt/local/bin:/opt/local/sbin/:$PATH export MANPATH=/opt/local/share/man:$MANPATH
