Hello, I try to install rtl-sdr and gnuradio on my computer, on Linux mint 18.1 cinnamon 3.2.7 64 bits. the installation is going well but when I try to execute rtl_test : Found 1 device(s): 0: Realtek, RTL2838UHIDIR, SN: 00000001 Using device 0: Generic RTL2832U OEM No supported tuner found Enabled direct sampling mode, input 1 Supported gain values (1): 0.0 Sampling at 2048000 S/s. I try intallling with a script and with pybombs, i have the same issue. My dongle have RTL2832 chip and FC0012 tuner it works on windows, and it works when i use "linux live gnuradio dvd". And it works if I start on "linux live gnuradio dvd" and reboot after on linux mint. Thank you for your help Best Regards Lidoro
