TerraTec Cinergy T Stick

TerraTec Cinergy T Stick is a USB 2.0 DVB-T device.

Currently not supported by LinuxTV. The manufacturer's Linux page links to vendor driver.

Based on:

• Afatech AF9035
• Infineon TUA9001

Install instructions for manufacturer driver

Method A

This method install the same drivers as in section B, with some small patches and a Makefile that directly creates the kernel modules, without compiling a whole kernel. The patches are (as in method B): to support the alternative USB code of the stick; to correct the frequency calculations.

• Download kernel source and headers equal to the ones you are using (check with 'uname -a'); e.g., for a Debian or Ubuntu distribution,

apt-get install linux-source-2.6.30 linux-headers-2.6.30-1-686 kernel-package

• and unpack the kernel source

 cd /usr/src ; tar xjf linux-source-2.6.30.tar.bz2

• Download the pre-patched drivers from http://tonelli.sns.it/pub/mennucc1/terratec_af9035-a_m.tar.gz and unpack it
• Edit the Makefile to point to the correct kernel directories
• compile

make

• install (as root)

make install

• Copy firmware (dvb-usb-af9035-01.fw) to /lib/firmware.

Method B

• Download the driver from Terratec http://linux.terratec.de/files/terratec_af9035.zip.
• Apply patch (AF9035-AF9033-TUA9001_DRIVER.patch) to kernel source, ignore the other files.
• Copy firmware (dvb-usb-af9035-01.fw) to /lib/firmware.
• The stick come with two different identifications, either 93 or AA . Check the USB identifier of the stick using 'lsusb' ; if you see 'AA' in a line such as

ID 0ccd:00aa TerraTec Electronic GmbH 

then you should edit the file drivers/media/dvb/dvb-usb/dvb-usb-ids.h and change the line from

#define USB_PID_TERRATEC_CINERGY_T_STICK		0x0093 

to

#define USB_PID_TERRATEC_CINERGY_T_STICK		0x00AA

• Apply the following patch to the tuner code.

• Configure and compile your kernel

• Have a beer

Tested with 2.6.30.1, in case the patches fail just work them in by hand. Don't give up!

Method C

Patch for adding device USB IDs to the manufacturer's driver.

Install instructions

• copy above patch to file (e.g. TerraTec_Cinergy_T-Stick.patch) and save it your home directory
• download driver from TerraTec support site

wget http://linux.terratec.de/files/Linux-Driver-for-T-Stick.rar

• extract driver package

unrar x Linux-Driver-for-T-Stick.rar

• enter driver directory

cd Linux_PC_AF9035_Afatech_2008.12.17/

• enter driver directory according to your Kernel architecture
  • for 32 bit

cd Linux-32bit_AF9035_20081217/

• • for 64 bit

cd Linux-64bit_AF9035_20081217/

• extract driver package

tar zxvf AF903x_SRC.tar.gz

• enter driver directory

cd AF903x_SRC/

• apply patch (from home directory)

patch af903x-devices.c ~/TerraTec_Cinergy_T-Stick.patch

• compile

make

• install (as root)

make install

Device should work if everything goes correctly. Few distribution specific install commands you may wish use:

Fedora:

su -c "make install"

Ubuntu:

sudo make install

Driver does support Kernels from 2.6.16 to 2.6.27. If you have newer Kernel then you could try compile it against 2.6.27 headers (cp v4l/kernel-2.6.27/* ./). In that case there is big risk it doesn't work and crashes your Kernel when device is plugged.
