Johannes, For now Mauro Chehab is the maintainer for Siano tuners. Guys from Siano stops to send patch a long time ago. I’m using SMS2270 (Siano RIO) with ISDB-T. But your log shows "DVB-T Europe”. Are you trying to tune ISDB-T Terrestrial stations as your firmware file name suggest? Try to enable debug inserting these options inside some file in /etc/modprobe.d/ options smsusb debug=3 options smsmdtv debug=3 and be sure your firmware is loaded. regards, - Roberto Em 16/07/2014, à(s) 09:14, Johannes Werner <johannes.werner@xxxxxxxxxxxxxxxxxxxxxx> escreveu: > Dear all, > > I hope this is the right place to ask for help / clarification > (linuxtv.org/ suggests it).
