Conexant cx24120/cx24118 dvbs

Whynot · 01-06-2018, 05:20 PM

Hi everyone
I have a Conexant CX24120/CX24118 dvb-s tv card under Ubuntu 17.10 64X system.I think its allready installed.
But there is no device called /dev/video0 and most of the softwares are working with this device how could we activate this device?

Code:

Device nodes /dev/video* are created by V4L drivers, yours is DVB.

Whynot · 01-07-2018, 06:04 PM

do you have any other recommendation?

Code:

sudo wget https://github.com/OpenELEC/dvb-firmware/blob/master/firmware/dvb-fe-cx24120-1.20.58.2.fw?raw=true -O /lib/firmware/dvb-fe-cx24120-1.20.58.2.fw
sudo reboot

that doesn't help either

Whynot · 01-08-2018, 07:07 AM

Here are some errors while restart process

Code:

$ dmesg

By the way I have 64 bit Ubuntu system

Code:

$ uname -i
x86_64

Could it be that problem?

Emerson · 01-08-2018, 01:17 PM

I think you misunderstood. Yours is digital device and it will not have /dev/video nodes.

Whynot · 01-09-2018, 05:57 AM

I got it but It still wont work with this devices

Code:

$ ls /dev/dvb/adapter0/
ca0  demux0  dvr0  frontend0

Kaffeine Tvtime or mplayer....

Emerson · 01-09-2018, 07:07 AM

Won't work. Would you be able you help me if I told you I couldn't get to work today? No. You would ask why, what happened.
So I'm asking, how it does not work. Error messages when started from a terminal. Did you use any DVB command line utilities to test your device? You may need to install dvbutils or dvbtools or whatever it is called in Ubuntu. Please, make it a little bit easier to help you.

Whynot · 01-09-2018, 07:21 AM

ok Kaffeine recognizes the conexant device but when I try to Search Satellite Channels it gives error called device not found.

A quick DuckDuck ... gives us this: https://forum.ubuntuusers.de/topic/c.../#post-8923893

Whynot · 01-09-2018, 09:06 AM

Yes.Im the same person there.Im tring to solve this issue.

Emerson · 01-09-2018, 09:11 AM

So what is the issue with the firmware, you never mentioned it here. Is there anything firmware related in dmesg?

Emerson · 01-09-2018, 09:20 AM

Is your card one of these?

Whynot · 01-09-2018, 07:10 PM

Sorry but I try every single thing I find in google.I don't know whether it works or not.
It works under windows 7.

I did also tried to change pci slot in motherboard.But nothing has changed.

$lspci -v |grep -i 'Sky'

I think this is my dvbs card.

no hope
thanks have nice day.

You do not need to build any drivers, at least for now. Did you notice your card needs several kernel modules loaded? It looks like for some reason not all drivers are loaded. You could use a live multimedia-oriented Linux CD to boot and get the listing with lsmod.
