This card '''supported''' (but not working properly)(???) in the stock kernel as of version 2.6.29 [http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=9e0dc6606a4f26a70cede6bf181cbff21f4c5477 commit].
There are experimental drivers available for the device (see [http://jusst.de/manu/stb0899-v4l-dvb.tar.bz2 http://jusst.de/manu/stb0899-v4l-dvb.tar.bz2]) , however, there are several areas that need improvement. There may also be some more recent patches available, but you will have to search the m/l archives to determine that for sure.

* [[STMicroelectronics]] [[STMicroelectronics LNBP21|LNBP21]] (LNB supply and control IC)
It also supports an add-on [[CI]] slot using the '''budget_ci''' module.


===Identification===
Public information on the STB0899 is limited. Although some documentation can be found (for example, Comtech Technology has a [http://comtech.myweb.hinet.net/pdf/dvbs2-6899.pdf product brief] for a tuner module, containing the STB6100 & STB0899, that outlines some basic register and timing info), what is available is not very useful. In fact, as has been related by the driver's author, the chip is rather complex and even with possession of its datasheet, the chip's vendor had to be consulted on numerous occasions about un-published/documented features and inaccuracies within the specifications. And although STMicro has been very accommodating, the driver development was, and continues to be, done under a [[NDA]]. Further, this situation is quite unlikely to change.

and making sure that the appropriate kernel modules are loaded.

Only start looking at experimental drivers described below if you need more recent changes or fixes.

===Card only rarely locks onto any transponder===

This is a known issue, and there is a patch available for it. First you have to get v4l-dvb source, instructions to do this can be found at [[How_to_Obtain,_Build_and_Install_V4L-DVB_Device_Drivers]]. Next, you need to apply this patch: [https://linuxtv.org/patch/4573/ Patchwork V4L/DVB: faster DVB-S lock for mantis cards using stb0899 demod]


I welcome anyone to improve my instructions as they are messy (no time to figure out how to do this properly), but this will work:

* Go to your media_build/linux directory.
* Make a new textfile called "stb0899.patch". Copy/paste the contents of the patch into it and save the file.
* Change a/ and b/ everywhere in the file to ./ so the paths point to your local files.
* Go to the commandline, cd to your media_build/linux directory.
* Run "patch -p0 < stb0899.patch". If you get messages about failed hunks, godspeed.
* Compile and install v4l-dvb. Reboot/reload modules.

Now, DVB-S transponders will lock reliably. I still see DVB-S2 transponders sometimes not locking properly in kaffeine and I will investigate whether this problem is kaffeine-related or if "scan" has the same problem. I've seen enormous data corruption occuring when tuning a DVB-S2 transponder, like there is a thunderstorm, but restarting kaffeine generally solves it. For now, this patch upgrades the S2-3200 from being a paperweight (it's too light for that really, I suggest using it as a bookmark) to a completely capable DVB-S tuner that, with some persuasion, can even be used for DVB-S2.

===Status/problems===

A problem with locking high symbol rate channels (DVB-S2 30000 3/4 transponders) has been reported a number
of times:
http://linuxtv.org/pipermail/linux-dvb/2009-January/031673.html,
http://linuxtv.org/pipermail/linux-dvb/2009-February/031779.html .
it is solved, buffer was too small. Unfortunately there's a tuning bug, but if you use 29998 instead of 30000 everything is working fine now.


Such transponders can be found at [http://www.lyngsat.com/hd/1west.html Thor 0.8W] and [http://www.lyngsat.com/hd/hispa.html Hispasat 30.0W].

A way to use the similar (but USB) [[TechnoTrend TT-connect S2-3650 CI]] to help fix problem has been suggested here:
http://www.spinics.net/lists/linux-media/msg01169.html .

Another way is to use 29999.999MHz for symbol rate. ( Successfully test with Eutelsat W2 / EuroBird 16E, Madagascar beam with OrangeTV)

Do you have the TT3200 or TT3650 ? Can you help debug the driver?

Also there is an issue with low symbol rates, anything below 5 Msymbols/s 5000.0MHz is not supported by the driver though the card as per vendor information supports as low as 2000MHz. So if you plan to use satelites with many services that has symbol rates below 5, this card will be of no use. [https://bbs.archlinux.org/viewtopic.php?id=233339]

===v4l-dvb/S2API driver===

Since kernel 2.6.28, DVB-S2 support has been implemented in the Linux kernel by means
of a new API, version 5, also known as [[S2API]].

Try the latest linuxtv.org repository, which is known as v4l-dvb. Changes here will go into the
next kernel version: [[How_to_Obtain,_Build_and_Install_V4L-DVB_Device_Drivers]].

ln -s s2-liplianin s2 [scan-s2 Makefile expects this]
cd s2-liplianin
make
sudo make install
sudo reboot

Scan for channels with scan-s2:
hg clone http://mercurial.intuxication.org/hg/scan-s2
cd scan-s2
[check the INCLUDE line in the Makefile points to the s2 directory]
make
./scan-s2 [options] -o zap dvb-s/[satellitefile] > ~/channels.conf
and tune with szap-s2:
hg clone http://mercurial.intuxication.org/hg/szap-s2
cd szap-s2
[check the INCLUDE line in the Makefile points to the s2 directory]
make
./szap-s2 [options] -c ~/channels.conf [channel]

Or install one of the main multimedia applications like [[Kaffeine]] or [[MythTV]].

===Multiproto driver===
A driver using the obsolete [[multiproto]] API may be installed as follows.

Installing on Debian (2.6.18-6-686) etch with Multiproto diver (!!!DVB-S2 Don`t Work. Only DVB-S!!!).
Install new Debian (2.6.18-6-686)

A DVB-S2 PCI card from TechnoTrend.
