I just reinstalled Ubuntu on my computer, I compiled GNURadio from source. I’m now running GNU Radio Companion 3.7.6git-1-g01deede3 With GNU Radio Companion I can access and listen to radio stations on my RTL-SDR dongle just fine. However today I just received my HackRF radio. Now, using the “osmocom Source” & HackRF I receive the following error msg. “FATAL: No supported devices found to pick from” Is there a driver I need to download for HackRF, if so where & how to I add that to my system? Thanks George ---

You need libhackrf. And you’ll probably need to recompile gr-osmosdr after installing it: > **[GitHub - greatscottgadgets/hackrf: low cost software radio platform](https://github.com/greatscottgadgets/hackrf#software-setup)** > > low cost software radio platform Mike ---

George - I just finished doing the same thing for my shiny-new Hackrf. Here is what worked for me on the same Ubuntu and GNURadio: sudo apt-get install hackrf-tools Add a one-line file to enable USB access to hackrf. sudo gedit Start a new file and enter this one line: ATTR{idVendor}==“1d50”, ATTR{idProduct}==“6089”, SYMLINK+=“hackrf-one-%k”, MODE=“660”, GROUP=“plugdev” Right-click on the file tab, click Save As, click on Computer, then go to this directory: /etc/udev/rules.d Enter this file name: 52-hackrf.rules then click Save. Exit gedit _Reboot_\* \* With Hackrf One plugged in to USB, test it: hackrf\_info A few lines of data should display. Doug ---

When I run “sudo apt-get install hackrf-tools” I get the following: “E: Unable to locate package hackrf-tools”. I then assumed that the command should be “sudo apt-get install hackrf”. That seemed to install something. I then added the needed line to 52-hackrf.rules and rebooted. Now when I run hackrf\_info I received the following: hackrf\_open() failed: HACKRF\_ERROR\_NOT\_FOUND (-5) What else am I missing? George ---

I had this same issue with a newly arrived unit. I had installed libhackrf and hackrf\_tools from the Ubuntu packages, then from a tarball version 2014.08.1 The problem was that the Ubuntu libhackrf was still in /use/lib and without LD\_LIBRARY\_PATH set, it got used instead of the new one in /usr/local/lib. The answer was to either: - Uninstall the Ubuntu libhackrf (best) or - Install the new version into /usr instead of /usr/local or - set LD\_LIBRARY\_PATH=/usr/local/lib (worst) > > Now when I run hackrf\_info I received the following: > > hackrf\_open() failed: HACKRF\_ERROR\_NOT\_FOUND (-5) > > Are you in the group that was mentioned in that line you added? > > Does an OpenMoko show when you do lsusb? > > Who owns the device /dev/bus/usb/bus-from-usb/number-from-lsusb? This is what you should see: $ lsusb … Bus 002 Device 005: ID 1d50:6089 OpenMoko, Inc. … $ ll /dev/bus/usb/002/005 crw-rw---- 1 root plugdev 189, 132 Sep 14 16:01 /dev/bus/usb/002/005 $ id … groups=…,46(plugdev),… $ ll /dev/hackrf-one-2-4 lrwxrwxrwx 1 root root 15 Sep 14 16:01 /dev/hackrf-one-2-4 → bus/usb/002/005 I got the same error as root too.
