TerraTec Cinergy DT USB XS Diversity
subsystem ID: 005a:0ccd
features two tuners, and have two antennas. You'll have adapter0 and adapter1 in /dev/dvb, which you can use separately.
The "Diversity" option is a hardware based feature that allows for the device's two receivers to be configured in a combined use mode to achieve better reception on a single channel. The diversity feature of the DiBcom demodulators is currently not implemented in the Linux-DVB drivers, so only the dual tuner configuration is presently supported on such devices .

Distro: Ubuntu Feisty, AMD64
The drivers shipping with Feisty are not recent enough, so downloaded & compiled & installed the current v4l-dvb distribution ( - you need to install & use Mercurial to fetch the source).
(You can also download an archive through Mercurial's web interface )
Downloaded the new dvb-usb-dib0700-03-pre1.fw firmware from  & copied it to /lib/firmware
(note: the following is likely dated by now)

Compiling the driver vv4.tgz from http://www.chez.com/treza/mt2266.htm
(on my system a netdevice.h was needed in /lib/modules/184.108.40.206-ccj51-default/build/include/linux)
Copying the firmware dvb-usb-dib0700-01.fw to /lib/firmware
Reboot, connect the stick, kaffeine, enjoy.
