A combined DVB-C, DVB-T and DVB-T2 USB 2.0 device from TechnoTrend. There are two different versions of the tuner. Version 1 is supported since kernel 3.17. Version 2 requires a small patch, which will probably be included in 3.19. The patch for 4400v2 is in media_tree and can be built using media_build for older kernels.
DVBSky T330 appears to be the same device with different USB ID.

Firmware
Firmware for both the demodulator and tuner are necessary. OpenELEC dvb-firmware collection includes firmwares for this device too.
- dvb-demod-si2168-a30-01.fw
- dvb-tuner-si2158-a20-01.fw
Place the 2 firmware files in /lib/firmware.
CT2-4400v2
If you have the second version of the device, you will need a different firmware for the demodulator. Just get the file dvb-demod-si2168-b40-1.fw from OpenELEC dvb-firmware collection.
IR Remote Control
The supplied remote control is supported by the driver.
