UHD Driver for USRP1 not found

Hello,

I am a high school student who has been working with gnuradio. I have
been trying to reinstall gnuradio with UHD, but am getting the No
device error. In internet searches, I have found others who have had
the same error, but I have not found the solution to the problem.

I installed per redmine and ettus instructions below (also included
prior dep.)
For UHD:

git clone git://code.ettus.com/ettus/uhd.git

cd uhd/host
mkdir build
cd build
cmake …/
make
make test
sudo make install

for gnuradio

git clone git://gnuradio.org/gnuradio
cd gnuradio
cd build
make
make test

sudo make install

sudo ldconfig

The gnuradio-companion works with dial tone example. However it cannot
find my USRP 1, giving the following error:

linux; GNU C++ version 4.6.1; Boost_104601; UHD_003.004.001-27-g93d4a16f

return _uhd_swig.usrp_source(*args)
RuntimeError: LookupError: KeyError: No devices found for ----->
Empty Device Address

The uhd_find_devices command returned the following:

linux; GNU C++ version 4.6.1; Boost_104601; UHD_003.004.001-27-g93d4a16f
No UHD Devices Found

Finally, when I checked in ~/uhd/host/build/lib/usrp/usrp1, it was
empty. So, I am wondering if there was another step I needed to
perform to be able to use my USRP1 with the UHD.

I really appreciate any help you can give me!

Many thanks,
J.

was usrp1 one of the configured components?
If not you need to install libusb1.0-dev

http://files.ettus.com/uhd_docs/manual/html/build.html#libusb

make
make test
sudo make install

Did you do the post install tasks? like installing udev rules?

Dear Mr. Blum,

Belated thanks for your advice. I did install libusb1.0-dev and the
post install tasks, but I still got the same error as before (the
devices not found error ) and the computer did not recognize the
USRP1. I will keep trying though, thanks for your advice!

Many thanks,
J.

Dear Mr. Leech,

Thank you so much for your advice! I did use the build-gnuradio script
on my Mint operating system, and the USRP1 is now being recognized. I
still unable to get sound out of my AM/FM demodulation flowgraphs due
to underrun errors, but I will keep trying to work them out. Thank you
so much, I really appreciate the advice.

Sincerely,
J.

If you’re on a Fedora, Ubuntu, or Debian Squeeze system, you can use:

http://www.sbrac.org/files/build-gnuradio

Which will take care of fetching/building all the latest UHD and Gnu
Radio software, as well as install the pre-requisites, and take care of
the
post-install tasks.
