TerraTec Cinergy T Stick+ is a USB 2.0 DVB-T with device id 0ccd:00d7 based on Realtek RTL2832U and the tuner Elonic E4000

Foreword: TerraTec_Cinergy_T_Stick / 0ccd:00aa is a different device, based on Afatech AF9035

First check that you have the right device

$ lsusb -d 0ccd:00d7
Bus 001 Device 008: ID 0ccd:00d7 TerraTec Electronic GmbH

Supported from Linux kernel 3.7 onwards (source Antti Palosaari)

In case you have an earlier kernel version, you might build the module as follow:

$ git clone git://linuxtv.org/media_build.git

$ cd media_build

Then follow the instructions as described in the "README" file

Thereafter you might load the module:

$ sudo modprobe -v dvb_usb_rtl28xxu
insmod /lib/modules/3.2.0-39-generic-pae/kernel/drivers/media/dvb-core/dvb-core.ko 
insmod /lib/modules/3.2.0-39-generic-pae/kernel/drivers/media/dvb-frontends/rtl2830.ko 
insmod /lib/modules/3.2.0-39-generic-pae/kernel/drivers/media/rc/rc-core.ko 
insmod /lib/modules/3.2.0-39-generic-pae/kernel/drivers/media/usb/dvb-usb-v2/dvb_usb_v2.ko 
insmod /lib/modules/3.2.0-39-generic-pae/kernel/drivers/media/usb/dvb-usb-v2/dvb-usb-rtl28xxu.ko 

You might check using dvbsnoop

$ dvbsnoop -s feinfo
dvbsnoop V1.4.50 -- http://dvbsnoop.sourceforge.net/

You may test you device using either dvbscan, scan, w_scan or tzap.

I've chosen Zap because it gives a quick feedback on the signal quality:

$ tzap 'la une'
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
reading channels from file '~/.tzap/channels.conf'
tuning to 754000000 Hz
video pid 0x0021, audio pid 0x0022
status 00 | signal bf81 | snr 0000 | ber 0000ffff | unc bf814ff8 | 
status 00 | signal bf81 | snr 0000 | ber 0000ffff | unc bf814ff8 | 
status 00 | signal bf81 | snr 0000 | ber 0000ffff | unc bf814ff8 | 
^C

NOTE 1: I've stopped the execution using control-c signal.

NOTE 2: Even if my device is recognized, I did not successifully managed to view a television channel - I'll get back and edit this page once I've more insight. (your help is welcome as well !)
