Making it Work
In case you have an earlier kernel version than 3.7, you might build the module as follow:
First check that you have the right device
$ lsusb -d 0ccd:00d7 Bus 001 Device 008: ID 0ccd:00d7 TerraTec Electronic GmbH
In such case, get the latest sources
$ 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 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 !)
