Thank you to Jérôme for giving me this solution: sudo nano / etc / default / tlp Then add the following line: USB_BLACKLIST = "1d50:6089 1d50:604b"

Installing and running GNURadio-companion and getting it to work on Windows 10 was easy. Not so on Linux, but after seven full days of trials and repeated failure, I now have my HackRF working with GNURadio-companion on my Ubuntu laptop; however, every time I execute a radio, I have to disconnect and reconnect the HackRF or else GNURadio-companion can not find the HackRF again. Any quick suggestions on how to improve its memory? For anyone that is interested, my installation started with resetting my Dell XPS13 to a factory-fresh Ubuntu 18.04 configuration, then executing the following commands: sudo apt-get install build-essential cmake libusb-1.0-0-dev pkg-config libfftw3-dev git clone https://github.com/mossmann/hackrf.git cd hackrf/host mkdir build && cd build cmake ../ make sudo make install sudo ldconfig rm -rf * hackrf_info cd ~ sudo apt-get install gnuradio gnuradio-dev gr-iqbal sudo apt install gqrx-sdr sudo apt install git git clone git://git.osmocom.org/gr-osmosdr cd gr-osmosdr mkdir build && cd build cmake ../ make sudo make install sudo ldconfig gnuradio-companion
