DVB-C USB stick recognized, /dev/dvb not available (therefore device not visible in TV Adapters)

Added by A AAA over 2 years ago

On QNAP QTS 4.5 the 2x TV Butler DVB-C sticks (quivalent to Logilink VG0022A using firmware dvb-usb-it9303-01.fw) are recognized (manufacturer Dexatek Technology Ltd)

TVMosaic qnap app recognizes the sticks as tv adapters (but DVBLogic went out of business) therefore I assume drivers are loaded successfully

Hovever, /dev/dvb does not exist and therefore TVHeadend doesn't recognize them as DVB-C adapters.

I tried to rebuild /dv/dvb manually according to this (http://www.roland-gersch.de/dec2000/node6.html)

rm -rf /dev/dvb

mkdir /dev/dvb
chmod 755 /dev/dvb

for i in `seq 0 3`; do
        echo "Creating DVB devices in /dev/dvb/adapter$i" 
        mkdir /dev/dvb/adapter$i
        chmod 755 /dev/dvb/adapter$i
        mknod -m 0660 /dev/dvb/adapter$i/video0    c 250   `expr 64 \* $i + 0`
        mknod -m 0660 /dev/dvb/adapter$i/audio0    c 250   `expr 64 \* $i + 1`
        mknod -m 0660 /dev/dvb/adapter$i/frontend0 c 250   `expr 64 \* $i + 3`
        mknod -m 0660 /dev/dvb/adapter$i/demux0    c 250   `expr 64 \* $i + 4`
        mknod -m 0660 /dev/dvb/adapter$i/dvr0      c 250   `expr 64 \* $i + 5`
        mknod -m 0660 /dev/dvb/adapter$i/ca0       c 250   `expr 64 \* $i + 6`
        mknod -m 0660 /dev/dvb/adapter$i/net0      c 250   `expr 64 \* $i + 7`
        mknod -m 0660 /dev/dvb/adapter$i/osd0      c 250   `expr 64 \* $i + 8`
        chown admin /dev/dvb/adapter$i/*
done

cat /dev/dvb/adapter0/dvr0
cat: /dev/dvb/adapter0/dvr0: No such device or address

cat /dev/dvb/adapter0/frontend0: No such device or address

However there is no such device in frontend0 and dvr0 and the structue is removed on next reboot

Is there any way to use the dvb-c usb sticks with TVHeadend?

Thank you very much for your help!

that was it - also you can try running:

modprobe dvb_usb_af9035

This would automatically load anyway if it doesn't say it doesn't find the driver all you need to do next is to put the 2 firmware files I mentioned in my first post in /lib/firmware

Hi Florin Vlaicu

NAS booted, 2 firmware files put into folder, plugged-in DVB Stick: Both attempts failed:

[~] # lsmod|grep dvb
[~] # modprobe dvb_usb_af9035
modprobe: module dvb_usb_af9035 not found in modules.dep

I think you need the Video 4 Linux package for this version of qnap to be available:
https://forum.qnap.com/viewtopic.php?f=320&t=133540&start=15

Another option would to do it yourself. As far as I can tell you need to compile the V4Linux drivers from: https://www.linuxtv.org/wiki/index.php/How_to_Obtain,_Build_and_Install_V4L-DVB_Device_Drivers.
Here's a howto for wireguard (a different kernel module, but the same basic ideea): https://github.com/mpbecker/QNAP_TS231P2_wireguard

https://forum.qnap.com/viewtopic.php?f=320&t=133540&start=15

most recent version asks me to downgrade to QTS 5.0

Is there a way to trigger an updated Video 4 Linux version for the current QTS Version?

I'm not sure if I can handle this. I had a quick look and found a section for compiling kernel. Is a compiled kernel affecting QNAP updates? Does the downloadable video 4 linux package come as well with a compiled kernel?

Is there a way to trigger an updated Video 4 Linux version for the current QTS Version?

I posted a request on QNAP's forum

RE: DVB-C USB stick recognized, /dev/dvb not available (therefore device not visible in TV Adapters) - Added by A AAA almost 2 years ago

Hello Florin Vlaicu!
Finally I could get Video4Linux Drivers for QNAP
https://www.myqnap.org/product/v4ldrivers/V4LDrivers_1.20221206_x86_64.qpkg

Place both files in /lib/firmware (if you have root)
and then unplug and plug the devices - they should appear properly in /dev/dvb now

I plugged in and uplugged the Stick twice. Unfortunately same result as before:

[~] # cd /dev/dvb
-sh: cd: /dev/dvb: No such file or directory
[~] # lsmod|grep dvb
[~] # modprobe dvb_usb_af9035
modprobe: module dvb_usb_af9035 not found in modules.dep

According to https://www.myqnap.org/product/v4ldrivers/, the drivers are located at 

/opt/V4LDrivers/GPL-5.10.60/drivers/media

try and see if you can locate any ko files there.

Hi Florin Vlaicu!

Unfortunately so far no luck.

I performed the following steps:

Booted NAS

executed according to guide: https://forum.qnap.com/viewtopic.php?t=133540


[~] # insmod /opt/V4LDrivers/GPL-5.10.60/drivers/media/usb/dvb-usb-v2/dvb-usb-af9035.ko
insmod: can't insert '/opt/V4LDrivers/GPL-5.10.60/drivers/media/usb/dvb-usb-v2/dvb-usb-af9035.ko': unknown symbol in module, or unknown parameter

Then I changed to the directory:

[~] # cd /opt/V4LDrivers/GPL-5.10.60/drivers/media/usb/dvb-usb-v2/

insmod: can't insert 'dvb-usb-af9035.ko': unknown symbol in module, or unknown parameter

Then I plugged in the USB DVB stick:

insmod: can't insert 'dvb-usb-af9035.ko': unknown symbol in module, or unknown parameter

The 'unknown symbol in module, or unknown parameter' error appears as well in the guide. This Video4Linux drivers where newly compiled from GPL sources by QNAP_Stephane just a few days ago

This module is probably not compatible with kernel.
What return:

uname -a

Can you show me what symbols are missing for dvb_usb_v2.ko -- show me dmesg output from when you try to insert that module.
Perhaps the dvb_core module isn't loaded - Perhaps try loading that one first and then trying the other ones?

Can you show me what symbols are missing for dvb_usb_v2.ko

How?

-- show me dmesg output from when you try to insert that module.

Note: no kernel modules copied and no dvb stick plugged in

Since I already have these modules loaded, the symbols are present in my kernel, so I can see which modules provide them
it seems you need to load the mc and dvb_core modules.

# cat /proc/kallsyms | grep __media_device_register
ffffc0420fd1a993 r __kstrtab___media_device_register    [mc]
ffffc0420fd1a9ab r __kstrtabns___media_device_register  [mc]

ffffc0420fd13bf4 t __media_device_register      [mc]
# cat /proc/kallsyms | grep dvb_create_media_graph
ffffc0420ffd2ffa r __kstrtab_dvb_create_media_graph     [dvb_core]
ffffc0420ffd3011 r __kstrtabns_dvb_create_media_graph   [dvb_core]

ffffc0420ffbda44 t dvb_create_media_graph       [dvb_core]

Try running the following before loading those modules. I expct that these modules (mc and dvb_core) to compe with the kernel directly

modprobe mc dvb_core

You can also confirm that the modules loaded by running the following commands:

lsmod|grep mc
lsmod|grep dvb_core

I'm running ubuntu 22.04 on my raspberry pi. I didn't install a custom kernel or install any patches - just copied the missing firmware files (that I already linked above).
I think I mentioned earlier, newer linux kernels support the TV Butler tuner

The stick is still recognized with DVB Logic's software (Company stopped business meanwhile)

I don't know what to say now :P
seems the kernel doesn't have support for the tv tuners - mc.ko does the following:
https://www.kernelconfig.io/config_media_support?q=&kernelversion=5.10.60&arch=x86

Perhaps you could try to find mc.ko or issue the command separately:

modprobe mc
modrpobe dvb_core

RE: DVB-C USB stick recognized, /dev/dvb not available (therefore device not visible in TV Adapters) - Added by A AAA almost 2 years ago

mc and dvb_core is a kernel element and not part of video4linux, am I right?

I tried to find mc.ko on my system but I think it's not there. How can I install it on qnap?

RE: DVB-C USB stick recognized, /dev/dvb not available (therefore device not visible in TV Adapters) - Added by Florin Vlaicu almost 2 years ago

How did you install tvheadend? Did you use this: https://www.qnapclub.eu/en/qpkg/723 ? Perhaps there are some other required packages to install besides that one.
