TerraTec Cinergy DT USB XS Diversity
A DVB-T USB device from TerraTec.
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 [1].
User experiences
Date: 22.8. 2007
Distro: Ubuntu Feisty, AMD64
Kernel: 2.6.20-16-generic
The drivers shipping with Feisty are not recent enough, so installed the current v4l-dvb distribution ([2]. It can be downloaded through Mercurial's web interface (see 'bz2' & 'gz'). Otherwise, you'd have to install & use Mercurial to fetch the source.
Downloaded the new dvb-usb-dib0700-03-pre1.fw firmware from [3] & copied it to /lib/firmware (if that does not work, flash the stick with the latest firmware from Terratec on a Windows PC).
After these steps, the stick works - I was able to find channels & get TV out of them.
(note: the following is likely dated by now)
openSUSE 10.2 (i586) Kernel 2.6.22.1-ccj51-default
Compiling the driver vv4.tgz from http://www.chez.com/treza/mt2266.htm
(on my system a netdevice.h was needed in /lib/modules/2.6.22.1-ccj51-default/build/include/linux)
Copying the firmware dvb-usb-dib0700-01.fw to /lib/firmware
Reboot, connect the stick, kaffeine, enjoy.
