TerraTec-DT-USB-XS-Diversity-Stick

A DVB-T USB device from TerraTec.

It is supported under Linux.

Overview/Features

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].

It seems that either this tuner stick does not have a very sensitive tuner, or the small antennas that come with it are simply insufficient for real-life use, unless one lives next door to a broadcast tower and has a direct line-of-sight to it. It is thus likely that an external antenna with a builtin amplifier is needed when this tuner is used.

Components Used

Identification

Two identical looking devices are known. They can be distinguished by their USB ID:

  • The first device has USB ID 0ccd:005a. It is supported by the official sources (see below).
  • The second device has USB ID 0ccd:0081. It is supported by the official sources since 14.01.2009 – make sure your sources are up to date.

Note: 0ccd is the Vendor USB ID (VID) of TerraTec, while 005a and 0081 are the Product USB ID (PID) of the sticks.

Making it Work (generic for all dib0700)

Firmware

August 21, 2008 - New firmware file fixing the last cause for i2c errors and disconnects and providing a new, more modular i2c request formatting.

You will need the dvb-usb-dib0700-1.20.fw firmware file in /lib/firmware or the relevant place for your distribution.

You may need to change the name of the file to dvb-usb-dib0700-1.10.fw or create a link until the driver code reflects that change.

For archival purposes: dvb-usb-dib0700-1.10.fw firmware file

August 29,2008 - Issues with Firmware 1.20. Some issues have been found with the latest version of the firmware. Users may wish to continue to use 1.10 unless they have patched their v4l-dvb code with dib0700_new_i2c_api.patch.

November 15,2008 - Issues with Firmware 1.20.

  • The above mentioned dib0700_new_12c_api.patch is not available discretely but is now rolled into the mercurial drivers
  • dvb-usb-dib0700-1.20.fw firmware file is now stable for reception, but remote control functionality is broken; any key press is repeated until the next key is pressed. The only way to get remote control functionality presently is to roll back to 1.10 firmware and suffer the occasional disconnect.
  • The mercurial drivers have been changed so they now load 1.20 firmware. To revert to 1.10 firmware you need to rename your firmware file to dvb-usb-dib0700-1.20.fw or provide a link of that name.
  • To avoid spurious remote control signals with 1.20 firmware, you need to edit /etc/modprobe.d/options or from Ubuntu onwards /etc/modprobe.d/options.confand add:
options dvb_usb disable-rc-polling=1

November 28,2008 - i2c errors. Changes were made to the remote control drivers on November 16,2008 to correct the repeat key problem. The card is generally stable for dual tuner reception and remote control function with Firmware 1.20.

November 10,2009 - mt2060 I2C write failed. Possible regression of a driver bug raised against Ubuntu running 2.6.27-14 and 2.6.31-2.17 causing mt2060 I2C errors in MythTV useage with firmware 1.20. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/397696 Recommend check the kernel extensions listed here for Low Noise Activation and rc_polling are loaded with correct config file name for your distribution, EIT listings information is turned off until a suitable delay (500ms-1000ms)is added to a single card (not both) and the card has correctly been added to the database as two tuners (no additional NULL entries) in the mythtv recordcard table.

Drivers

It requires the dib0700 driver. Just use Mercurial by following the How to Obtain, Build and Install V4L-DVB Device Drivers instructions.

Forcing the activation of LNAs (Low Noise Amplifier)

You may have to force LNA to get this card working:

In /etc/modprobe.d/options add:

options dvb_usb_dib0700 force_lna_activation=1

Disabling the remote control sensor

You may want to disable the remote control sensor if you are using another one and want to avoid error messages in the logs:

In /etc/modprobe.d/options add:

options dvb_usb disable_rc_polling=1

All relevant kernel modules options

In /etc/modprobe.d/options add:

options [module name] [option name]=[setting]

Get the parameters list using

modinfo [name of kernel module]

The debug values are bit fields, with each bit representing a different category. Add values to turn on multiple debugging categories.

Remote control support

Using evdev

As long as the evdev module is loaded, a remote that is recogniced as hid device will be treated as a usb keyboard and this means that you can avoid using lirc.

However, many of the keys on your remote may generate keycodes which are not mapped to anything, by default.

In X you can use xev to find the keycodes and xmodmap to map them to useful symbols. Unfortunately, some keys may generate keycodes that X doesn't recognize at all and the device does not support keymaps, or this would be easy to fix.

Using LIRC

Usually remote controls in linux are managed by the lirc software collection.

To get lirc up and running you need to configure some things.

  • Settings for the hardware
    • Where does lirc get its input from? aka. the DEVICE. E.g. /dev/input/event3
    • How to handle the input? aka. the DRIVER. E.g. devinput
  • Settings for mapping driver output generated by your remote (a bunch of hex numbers) to key names (something like 0..9, Volume+, Next, Record)
  • Settings for mapping key presses to actions (usually located in your .lircrc)
Mythubuntu case

On mythubuntu 10.10, you just have to add this line in /etc/udev/rules.d/65-persistent-hauppauge.rules

SUBSYSTEM=="input", KERNEL=="event*", ATTRS{idVendor}=="2040", ATTRS{idProduct}=="8400", SYMLINK+="lirc0"
Device/driver settings

Find the IR receiver's device by looking in the dmesg output for a line similar to:

input: IR-receiver inside an USB DVB receiver as /class/input/input4

Additionally, the IR receiver will be listed if you execute the command:

cat /proc/bus/input/devices

For example:

I: Bus=0003 Vendor=2040 Product=9950 Version=0100
N: Name="IR-receiver inside an USB DVB receiver"
P: Phys=usb-0000:07:01.2-1/ir0
S: Sysfs=/class/input/input4
U: Uniq=
H: Handlers=kbd event4 
B: EV=3
B: KEY=14afc336 284284d00000000 0 480058000 219040000801 9e96c000000000 90020000000ffd

In this example, the remote control gives output into /dev/input/event4.

The event number depends on your particular system and can vary.

Eventually this event number can even vary at every reboot.

You could create a new udev rule in /etc/udev/rules.d/65-persistent-hauppauge.rules.

KERNEL=="event*", ATTRS{name}=="IR-receiver inside an USB DVB receiver", SYMLINK+="input/dvb-ir"

This would make IR receivers handled by the usb_dvb framework always always be linked to /dev/input/dvb-ir.

But Linux systems running recent udev will automatically create non-varying names, a nicer and automatic way of providing a stable input event name:

$ ls -la /dev/input/by-path/
total 0
drwxr-xr-x 2 root root 140 2008-02-07 20:31 .
drwxr-xr-x 4 root root 280 2008-02-07 20:31 ..

lrwxrwxrwx 1 root root   9 2008-02-07 20:31 pci-0000:00:1a.1-usb-0:2:1.1-event-mouse -> ../event2

lrwxrwxrwx 1 root root   9 2008-02-07 20:31 platform-pcspkr-event-spkr -> ../event3

LIRC will use it without needing a special kernel module. use the dev/input (or devinput. Check this with the command "lircd --device=help".) driver and specify the input event device in /etc/lirc/hardware.conf

# /etc/lirc/hardware.conf
#
# Arguments which will be used when launching lircd
LIRCD_ARGS=""

#Don't start lircmd even if there seems to be a good config file
#START_LIRCMD=false

#Try to load appropriate kernel modules
LOAD_MODULES=true

# Run "lircd --driver=help" for a list of supported drivers.
DRIVER="dev/input"
# If DEVICE is set to /dev/lirc and devfs is in use /dev/lirc/0 will be
# automatically used instead
REMOTE_DEVICE="/dev/input/by-path/pci-4-1--event-ir"
MODULES=""

# Default configuration files for your hardware if any
LIRCD_CONF="/etc/lirc/lircd.conf"
LIRCMD_CONF=""

If you have REMOTE and TRANSMITTER sections in your hardware.conf file, they should look like this:

#Chosen Remote Control
REMOTE="Terratec Cinergy DT USB XS Diversity"
REMOTE_MODULES=""
REMOTE_DRIVER="devinput"
REMOTE_DEVICE="/dev/input/by-path/pci-1-5-event-ir"
REMOTE_LIRCD_CONF="/etc/lirc/lircd.conf"
REMOTE_LIRCD_ARGS=""
#Chosen IR Transmitter
TRANSMITTER="None"
TRANSMITTER_MODULES=""
TRANSMITTER_DRIVER=""
TRANSMITTER_DEVICE=""
TRANSMITTER_LIRCD_CONF=""
TRANSMITTER_LIRCD_ARGS=""
Remote key setup

See device specific section below or try [2].


Sample .lircrc

A sample .lircrc can be found LircrcExample here.

Keys repeated twice

But there is still the problem of the key repeats for it, so that each keypress will be repeated twice. The patches, as mentioned above, may not work, but a workaround is possilbe. It is described in http://ubuntuforums.org/showthread.php?p=4253678

Simply add config = echo " > /dev/null before the main config in .mythtv/lircrc or .lircrc

 begin
  prog = mythtv
  button = Mute
  config = echo " > /dev/null
  config = |
  ...
 end

So each 2nd keypress will be suppressed. This works in some application but not others (e.g. vlc).

Alternatively there is a patch for the kernel driver that solves it, it can be found here.

Finally if that doesn't work and you have the silver remote (A415-HPG-WE-A ) then changing the lircd.conf line as follows can prevent the duplicate key presses. This has the side-effect of disabling key repeats for the remote entirely. Change toggle_bit_mask 0x80000000 to toggle_bit_mask 0x00000000

Note: do not try to comment out (using #) any line in this file, or lirc won't work anymore.

Do NOT do this:

 #toggle_bit_mask 0x80000000
 toggle_bit_mask 0x00000000

Replace the original line instead.


Specific to the Model

Specific Remote control support

The remote is supported at least in the Mercurial repository (see Drivers section above).

TerraTec gray-orange remote
TerraTec Cinergy DT USB XS Diversity-remote.jpg

Apparently this remote is sold with (at least) the TerraTec Cinergy DT USB XS Diversity, TerraTec Cinergy 2400i DT, and TerraTec Cinergy T USB XXS.

The dvb-usb-dib0700 module needs to be loaded with the option dvb_usb_dib0700_ir_proto=0 to set the IR protocol to NEC (which is used by this device).

The following keycodes should work with it, specify them in /etc/lirc/lircd.conf:

# Please make this file available to others
# by sending it to <lirc@bartelmus.de>
#
# this config file was automatically generated

end remote

Note: the most recent model of this remote requires four different codes (replace them in above list).

          ab                       0x00AD
          ff                       0x00D0

          pic                      0x0177

Should you need to quickly test all possible keycodes, just use this script to generate a list, which you can copy/paste to your lircd.conf file:

 for (( i = 1; i < 512; i++ )); do x=`printf %#06X $i`; echo code$x $x; done

The result looks like this:

 code0X0001 0X0001
 code0X0002 0X0002
 code0X0003 0X0003
 code0X0004 0X0004
 ...
 code0X01FC 0X01FC
 code0X01FD 0X01FD
 code0X01FE 0X01FE
 code0X01FF 0X01FF

Copy these keycodes just after the begin statement of your lircd.conf file. You can leave the original keycodes, duplicated values are not a problem. Once lircd is restarted, run the irw program and press your remote keys to show the missing codes:

 # irw
 00000000000100ad 00 code0X00AD Cinergy_Hybrid_t_USB_XS
 00000000000100d0 00 code0X00D0 Cinergy_Hybrid_t_USB_XS
 000000000001019c 00 code0X019C Cinergy_Hybrid_t_USB_XS
