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.
Note that currently, with kernel 2.6.30, the remote does not work: the module 'hiddev' recognizes the stick as a keyboard, and offers it as a input device /dev/input/event?? (use 'evtest' to test it).
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.

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.
