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 .
Date: 22.8. 2007
Distro: Ubuntu Feisty, AMD64
The drivers shipping with Feisty are not recent enough, so installed the current v4l-dvb distribution (. 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  & 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.
Update: 19.11. 2007
Tuners using the dvb-usb-dib0700 module may be unable to tune to a particular channel multiplex while receiving others just fine. This appears to be a fairly common problem that is caused by some sort of amplifier setting not getting used when it should; look for lines with "filter timeout" when running 'scan', if you are missing all channels of a particular multiplex.
In short, if experiencing this problem, try setting the following (in /etc/modprobe.d/options or /etc/modules.conf):
dvb_usb_dib0700.force_lna_activation=1 </owiki> After the module has been reloaded, you might be able to find and view the missing channels :-) You can check /sys/module/dvb_usb_dib0700/parameters/force_lna_activation on your system to make sure the parameter has been set. Finally, this stick works just fine on 32-bit Ubuntu Gutsy as well. ---- (note: the following is likely dated by now) openSUSE 10.2 (i586) Kernel 220.127.116.11-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/18.104.22.168-ccj51-default/build/include/linux) Copying the firmware dvb-usb-dib0700-01.fw to /lib/firmware Reboot, connect the stick, kaffeine, enjoy. '''Update: 3.2.2008''' Tuner works partially fine with Kernel 2.6.24-gentoo + xorg-server-1.4 + kaffeine 0.8.6 with xine-lib-1.1.10 The mt2266 modul is now included in the main kernel tree. Unfortunatly the Diversity Mode (two tuners running as one for better receive) doesnt work. Furthermore the Windows receiver has a mucher better receive quality :-(. I.e. in Windows Im getting all 23(24) channels, in Linux only 19(20). == External links == * [http://tven.terratec.net/modules.php?op=modload&name=News&file=article&sid=251 TerraTec product page]
