Re: [Discuss-gnuradio] libusb error with gnuradio v3.4.2git

[Ralph A. Schmid, dk5ras]

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.

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.

What are you intending to do with this installation? 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 :)

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.

 

usrp_benchmark_usb.py returns:

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
