Firmware
Firmware for both the demodulator and tuner are necessary. OpenELEC dvb-firmware collection includes firmwares for this device too. Note that when downloading the firmware files from the OpenELEC firmware collection it's necessary to click the name of the firmware file first and then the "raw" button to download the actual binary!
- dvb-demod-si2168-a30-01.fw
- dvb-tuner-si2158-a20-01.fw
Place the 2 firmware files in /lib/firmware.
Two demodulators
Do note that the device has 2 demodulators. The built-in DVB-T demodulator in the RTL2832P chip as well as the external Silicon Labs Si2168 demodulator. Both demodulators will be attached and can be used. The driver will create 2 frontends for the same adapter:
crw-rw---- 1 root video 212, 5 May 4 19:33 net0 crw-rw---- 1 root video 212, 4 May 4 19:33 dvr0 crw-rw---- 1 root video 212, 3 May 4 19:33 demux0 crw-rw---- 1 root video 212, 7 May 4 19:33 frontend1 crw-rw---- 1 root video 212, 6 May 4 19:33 frontend0
Frontend 0 will be linked to the RTL2832P demodulator that only supports DVB-T. Frontend 1 will be linked to the Si2168 demodulator that supports also DVB-T2 and DVB-C modes. Note that you will need to use an application that is capable of handling multiple frontends.

IR Remote Control
The remote controller is currently unsupported. Support can be added relatively easy.
Known issues
Sometimes the loading of the firmware will fail for unknown reasons. Removing and installing the module again will usually help. After a successful firmware loading you should be able to see the firmware version numbers printed out in the system log. There's a patch [2] in kernel 4.6 that seems to help.
