Hi there, I am running an updated raspbian image with kernel 4.4.23-v7+, matching linux-headers-4.4.23-v7+_4.4.23-v7+-2_armhf from here: https://www.niksula.hut.fi/~mhiienka/Rpi/linux-headers-rpi/ and dvb-demod-si2168-b40-01.fw (see linuxtv-wiki). Before the last apt-get upgrade this works great, but now, it ends up in recognizing the device but not create /dev/dvb.

What I am doing wrong? The last git clone was approx. in August. 2nd question: Is there anything new in supporting both tuners of the dualHD stick?
