Hi, I think it can be a good idea to tighten the permissions in the udev rules a bit. In Fedora we use rtlsdr group for users authorized to access the HW, i.e. the following:
sed -i 's/MODE:="0666"/GROUP:="rtlsdr", MODE:="0660"/' ../rtl-sdr.rules Maybe a bit annoying on single user desktop, but definitely a good security practice for fine grained access to resources especially on servers thanks & regards Jaroslav
