What can I do to get this device working now? There is no option for I2C-gate, gate will be called every time when access to tuner is needed. If you already use MT2060 coming with AF9015 driver it should work. I doubt that you are mixing em2880 driver and af9015 and wrong tuner driver is coming from em2880. But I am not sure. Could you make clean install to see whether or not it is working. hg clone http://linuxtv.org/hg/v4l-dvb/ make make install (root privileges) replug stick reboot plug stick It should work (hopefully) reagrds Antti -- http://palosaari.fi/ _______________________________________________ linux-dvb mailing list linux-dvb@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
