I have a fresh install of Debian, I have installed kernel headers and most of the tools and libs for building and certainly all the requirements I am aware of to make this cards work with limited success.
I have spent a week on this with some success but I am sure there is something in the driver wrong or interfacing with the driver at higher level.
I have 2 problems here, firstly have I got this card actually working? And then if so why can't dvb tools scan read the transponders also why cant I update a the frequency data from the files in /usr/share/dvb/dvb-s directory?.
From the point of testing I would like to create a single new sat with a single transponder but cant do that or edit an existing and have the file read without parse failure?
scan will find the files ok even the originals untouched but fail to read them in.
Its really a case of 2 question posts but both would need the same material as I present here.
The MB is an Asrock AD410PV a lower end atom board, bios is their last update.
OS is debian buster 64 bit
Code:
uname -a
Linux wx 4.19.0-13-amd64 #1 SMP Debian 4.19.160-2 (2020-11-28) x86_64 GNU/Linux
This the card I have, I believe it to be version 2.7. Its got the flexcop2.
https://linuxtv.org/wiki/index.php/TechniSat_SkyStar_S2
First obvious problem was firmware so I found and installed dvb-fe-cx24120-1.20.58.2.fw which was mentioned to the the correct one.
I cant test it properly because I can't get dvb tools to work properly. But if it was OK TSDuck commands would work and that is all I want of it. The raw data stream from a single C band transponder. So first the card setup.

However in my card it fails on Cband but sort of works on Ku. The hardware input would not be related to this as its setup easily set 1278 megs by calcing with the LO offsets. But is this done in the driver it self or tools calling the driver.
Code:
hca@wx:~$ dvbtune -f 3872000 -p H -D 0 -tone 0 -s 3200 -m

Now I tune the the same IF as 11878megs KU band, ie tune the card to same 1278 megs, it has no error and finds the signal.
Code:
hca@wx:~$ dvbtune -f 11878000 -p H -D 0 -tone 0 -s 3200 -m

Next example the command I wish to run with TSDuck. The author tell me its a system generated message passed back rather than TSDuck generated, but neither frequency works. He has kindly tested the command line verbatim as being OK for me.
Code:

* Error: dvb: tuning error on /dev/dvb/adapter0/frontend0: Invalid argument
Here is the new dmesg outputs, all 4 examples loaded the same IF of 1267 into the tuner only dvbtune as ku worked, c band failed both times.

Next example is hca@wx:~$ w_scan -f s -s S108E2. There are 3 birds here, Sband, C band and Ku band. Scan works through Sband up to Ku, there will be eorors with Scand if its not in the tools because its not common and you just convert the channels up to Cband. A blind scan will find them as whatever band it thinks the lnb as. So ignore the first 9 failed sband frequencies. The only lnb connected is Cband with signals.

Every Sband frequency failed to try, ok the tool may not know Sband but every Cband channel has failed to even try.
Unfortunately all C band birds are migrating channels away from the lower transponders to higher ones over the last year to allow for 5G mobiles to use them. Meaning every supplied list will now be invalid untill it is updated.
It attempted every Ku channel but some have an error.
After that scan this we have only diseqc errors added to dmesg output, no tuning errors. It would be nice if diseqc worked but I don't actually need it. Ku band 22khz tone seems to be working.

But all is not quite right when I try to use it. I can't control it properly with dvb tools, below I tune to a signal present on 3872megs with an error.However there is a strong DBS-S signal there from the lnb.
Again on a Ku bird, with signal available, dvbtune finds it, scan fails.

This time the transponder is in the frequency list. but scan fails, 12603 and 12643 have signal but fail to find the data, in fact 12643 totally fails. Lyngsats lists the FEC as 3/5 the list has FEC as auto, I don't know why scan has them as 2/3 and 3/4.

The card does work ok in WES7 with supplied drivers but only for normal TV signals and I want the raw stream which this card will provide.
I have major issues with these command line DVB tools I should not have which should be a separate post,but I only need to define a new satellite with one Cband channel for my use. I don't need tone or diseqc if they are not supported.
However I can not get these tools to read the supplied satellite frequency lists led alone a new one or an edited one, always a parse error.
If the card was working, which I could prove if i could get these tools to work, I think the TSDuck command would work, it is proven 100% ok on other systems
I have not tried things like Kaffine as I set up a minimalist LXlite gui as the machine runs headless.Things like KDE and Gnome come with a lot of baggage I have no need of cluttering it up.
