Hi Juan,

That is great, because the other software works fine with the HackRF and
hackrf_info finds it and it is up to date, it means that your hackrf
hardware works and the drivers are all correctly installed and recognizing
it. The problem is in the set up or configuration gnuradio. I have found
the #gnuradio IRC channel on freenode to be helpful for configuration
issues like these.
