Hi pbg4, you are right, the Terratec S2 Box and Tevii S662 seems to be clones of the tt-s2-4600. I merged the patches of the following sites into the attached file: http://www.spinics.net/lists/linux-media/msg96109.html https://forum.ubuntuusers.de/topic/dvb-adapter-tevii-s662-mit-media-build/ It works! Thx. My only problem is to get the new module dvb-usb-dw2102 automatically loadeby immergut - Debian
