It's recognized and initialized. But the stick "uses a shared frontend for both DVB-T and DVB-C" as stated on linuxtv.org. On tvheadend (3.4.27-2 from https://aur.archlinux.org/packages/tvheadend/) when "add DVB network by location" only the dvb-c part can be chosen. But I want to use the DVB-T part, is there any way to convince tvheadend to scan dvb-t frequencies instead cable frequencies?
