A DVB-C USB device from TechniSat.

Overview/Features

A combined DVB-C and DVB-T USB 2.0 box (standard definition and high definition). The device contains a common interface slot and an integrated infrared receiver. A remote control is included.

It is supported by parching the device ids into the current releases of Linux.

Components Used

DRX 3913 JKA 2

CY7C68013A

EPM3128ATC144-10N

http://www.altera.com/cgi-bin/devsearch.pl?col=corp&qt=EPM3128

Identification

The USB id of this device is 14f7:0003

Making it Work

The Window drivers for this devices from TechniSat is named UDST7000Bda.sys, the same as the driver for the Technisat SkyStar USB 2 HD CI and TerraTec S7 DVB-S devices. These devices are supported by Linux with the az6027 driver. This gives some hope towards future Linux support for this device.

Firmware

dvb-usb-terratec-h7-drxk.fw dvb-usb-terratec-h5-drxk.fw and dvb-usb-terratec-h7-az6007.fw from http://linuxtv.org/downloads/firmware/ 0

Copy the firmware files to your hotplug directory (e.g. /lib/firmware/) and (when applied the patches from below) rename dvb-usb-terratec-h5-drxk.fw to dvb-usb-technisat-cablestar-hdci-drxk.fw

Drivers

As the TechniSat CableStar Combo HD CI is a clone of the Terratec T7 card which is supported in the kernel v3.9.2 some small patches are needed to get the card working.

When tuning, the dmesg shows two errors, which can safely be ignored:

Patch

These are the needed patches for the kernel 3.9.2 to get the device working. Also tested on Linux debian wheezy 3.10-0.bpo.2-686-pae

Step-by-step instructions

In this section I will provide step-by-step instructions how to patch and compile media_build for the TechniSat CableStar Combo HD CI. Though I compiled it on a debian wheezy system with backported kernel v3.10 it might probably also run on different systems (i.e. lower kernel versions) with very similar steps.

Commands preceeded by # are to be run with root privileges, whereas $ only requires user previliges.

First, you need to get the tools for building media_build by installing the packages git, build-essential, libproc-processtable-perl and patchutils. E.g. in debian, you want to run the command

# apt-get install linux-headers-$(uname -r) git build-essential patchutils libproc-processtable-perl

After that, you have to obtain the current media_build stack:

$ git clone git://linuxtv.org/media_build.git
$ cd media_build
$ make download untar

Next step is to apply the patches. Therefore, download the patch from here , save it to your media_build/linux directory (e.g naming it media-az6007-support-Technisat-Cablestar-Combo-HDCI-minus-remote.patch) and run:

$ cd linux
$ patch -p1 < media-az6007-support-Technisat-Cablestar-Combo-HDCI-minus-remote.patch

Now you are ready to make and install media_build, by first switching back to the media_build root directory and then using make and make install to complete installation:

$ cd ..
$ make
# make install

Finally, you need the above mentioned firmware to get the device working:

# wget http://linuxtv.org/downloads/firmware/dvb-usb-terratec-h5-drxk.fw -O /lib/firmware/dvb-usb-technisat-cablestar-hdci-drxk.fw
# wget http://linuxtv.org/downloads/firmware/dvb-usb-terratec-h7-az6007.fw -O /lib/firmware/dvb-usb-terratec-h7-az6007.fw

Credits for this workaround go to the Ubuntuusers.de forum (especially to the users hakunamatata and mczak) as well as Roland Scheidegger for providing the patch.

Linuxtv.org media_build

Some time in the future the device will be supported by the Linuxtv.org build system to use the latest experimental drivers/patches without needing to replace the entire kernel.

The system is available at http://git.linuxtv.org/media_build.git .
