Softlander · Does this dvb s2 tuner work? Softlander March 1, 2018 at 11:54 AM

Hello,

So I have a Raspberry Pi 3 now connected to the TT Connect s2-4600 with the official power supply and a 16GB microSD Card with latest Noobs installed on it and I have now a dual boot with Raspbian and Librelec.

On Libreelec I have managed to Install Tvheadend 4.2 and Tvheadend HTSP Client and then Rebooted the system.

After that I made sure the the PSU of the tuner is working by checking it using voltmeter. and I have checked /lib/firmware and I have found the three files that are related to the device installed already

1- dvb-fe-ds300x.fw

2- dvb-fe-ds3103.fw

3- dvb-demod-m88ds3103.fw

No, it does NOT !!!

Tested the above device ~2 weeks ago on last LE release and on some vanilla/distro kernels on Fedora 27 (x64_86)

ID 0b48:3011 TechnoTrend AG TT-connect S2-4600

=> BUG: unable to handle kernel NULL pointer dereference

see => BUG: unable to handle kernel NULL pointer dereference

same Bugs in

- DVBSky S960

- TerraTec Cinergy S2 Rev.4 (ID 0ccd:0105)

Technotrend and TerraTec was tested by me

esp. Technotrend I got an additional error message sort of "overcurrent on usb port xyz"

not so on TerraTec ...

If they would work I would go for a TerraTec again

And the result is : The device "does not" work, it has not been detected by tvheadend when I accessed it using mozilla Firefox from windows. Tvheadend worked but I did not find the device listed under DVB Inputs. Same case with Raspbian+tvheadend

So I have tried to install the drivers myself (I have installed linux headers and found build essentials already installed)

Code

sudo apt-get install raspberrypi-kernel-headers

but: "s2-TT4600-linux-20120815" and "liplianin-s2-liplianin-v37-67ce08afdbe7" and "liplianin-s2-liplianin-v39-4c01a16b6237" did not work. I am not an expert in Linux but I think these Drivers have been made for older Kernels.

Quote from CvH

worked for me O_o

not saying there is no bug, but no problems so far

How did you install the driver. Was it plug and play?

Here are some INFO using PuTTY during SSH with the Pi. Any ideas. Thanks to everyone.

Softlander · Does this dvb s2 tuner work? Softlander February 28, 2018 at 2:43 PM

Hello,

Does any one have tried this tuner:

"TechnoTrend Connect S2-4600 HDTV-S2 USB" With Latest LibreELEC?. I have read here TechnoTrend TT-connect S2-4600 - LinuxTVWiki that this tuner is supported since kernel 4.1

P.S: I have just started to use/learn raspbian/linux and I'm planning to use it as HTPC with this tuner.
