Any chance to make hybrid usb tv tuner work?

Hello and Merry cristmas!
I have a hybrid usb tv tuner which has anolg and digital signal. I have it about 5-6 years now but I never use it because it didn't find how to make it work on linux. I had an older pinnacle pctv hybrid usb tuner and I was using it, but it's broke now. So I give another shot to the newer device.
Dmesg has the above output when I connect it:

usb 1-2: new high-speed USB device number 12 using>
usb 1-2: New USB device found, idVendor=1b80, idPr>
usb 1-2: New USB device strings: Mfr=1, Product=2,>
usb 1-2: Product: Polaris AV Capture
usb 1-2: Manufacturer: Conexant Corporation
usb 1-2: SerialNumber: 0000000000
(END)

lsusb gives this:

Bus 001 Device 012: ID 1b80:d418 Afatech Polaris AV Capture

I also have extract the firmware and I copied in /lib/firmware. It is "v4l-cx25840.fw" its name.
Also I have open it and I get some info from the 2 chips it has inside.
The first is:

RTL 2832
BAD 70AJ
GB46D

And the second:

CX3102-11Z
N2F644.05
1031 GC

These are all I've got.
I don't know which module support it(if any) and if is installed and loaded.
Is there any chance to make it work?

Re: Any chance to make hybrid usb tv tuner work?

Step 1. When you issue dmesg -w
And then plug the device in, does it load the firmware and become ready for use?

Like this:

[50696.492907] usb 1-10: new high-speed USB device number 6 using ehci-pci
[50696.640460] usb 1-10: New USB device found, idVendor=2304, idProduct=023b, bcdDevice= 1.00

[50697.971464] dvb-usb: schedule remote query interval to 50 msecs.
[50697.971468] dvb-usb: Pinnacle PCTV HD USB Stick successfully initialized and connected

Step 2
After that works I recommend pacman -Si v4l-utils
It has a file called dvbv5-zap.
You can make a channels.conf with that or just make one manually with the center frequencies for the channels in your area.
https://en.wikipedia.org/wiki/Televisio … requencies

Step 3
Zap a channel out of your conf file and then anything will play it/record it.
Example:

conf="$HOME/.mplayer/dvb_channel.conf"
dvbv5-zap -ssrc "$conf" 14.1
mpv --vf=scale=768:432 /dev/dvb/adapter0/dvr0
ffplay /dev/dvb/adapter0/dvr0

Or use something like Kaffeine, Kodi

Edit:
Sorry, you make a .conf file with dvbv5-scan

No it doesn't. After I load the dvb_usb_rtl28xxu and rtl2832 module, when I connect the device there is no change:

[Σαβ Δεκ 28 15:09:43 2019] usbcore: registered new interface driver dvb_usb_rtl28xxu
[Σαβ Δεκ 28 15:10:13 2019] usb 1-2: USB disconnect, device number 4

Re: Any chance to make hybrid usb tv tuner work?

You are going to have to get/build working firmware for the device, if you can. Depends on how hard you want to work at it.

New USB device found, idVendor=1b80, idProduct=d418, bcdDevice=40.01

https://www.linuxtv.org/wiki/index.php/ … nformation
https://www.linuxtv.org/wiki/index.php/ … ce_vendors
https://cateee.net/lkddb/web-lkddb/VIDEO_CX231XX.html
https://www.linuxtv.org/wiki/index.php? … ldid=31581

This looks like the one that you chose. Has a different id.
https://www.linuxtv.org/wiki/index.php/ … id_Full_HD
https://www.kaa.org.ua/en/22-articles/6 … ll-hd.html

1b80:d418
https://sciencespaces.com/search/USB/VI … -PID_D418/
https://www.spinics.net/lists/linux-media/msg48485.html

This has some 1b80 in it.
https://www.linuxtv.org/wiki/index.php/ … SB_Devices

And they use.
dvb-usb-it9137-01.fw
dvb-usb-af9015.fw

More info

lsusb -v -d 1b80:d418

Post back if/when you get it working so everyone else will know.
Good luck.
