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

A AAA

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!

Rename the attached file to 60-tvbutler-perms.rules and copy it to /etc/udev/rules.d

Then run:

Thank you very much for your reply!

I downloaded https://github.com/uglymagoo/plexmediaserver-installer/blob/master/lib/udev/rules.d/60-tvbutler-perms.rules with the contents
SUBSYSTEM=="usb", ATTRS{idVendor}=="1d19", ATTRS{idProduct}=="0100", GROUP="video", MODE="0664"

and copied the file to /etc/udev/rules.d

Note: GROPUP="video" - I don't have a group with this name.
groups

administrators everyone

Should I replace it with administrators?

[/etc/udev/rules.d] # ls -lisa total 148 37321 0 drwxr-xr-x 2 admin administrators 80 2022-04-30 08:25 ./ 37320 0 drwxr-xr-x 3 admin administrators 80 2022-04-30 08:21 ../ 347361 144 -rw-r--r-- 1 admin administrators 143571 2022-04-30 08:25 60-tvbutler-perms.rules 37322 4 -rw-r--r-- 1 admin administrators 636 2022-01-28 01:12 65-drbd.rules [/etc/udev/rules.d] # sudo udevadm control --reload-rules [/etc/udev/rules.d] # sudo service udev restart sudo: service: command not found

Unfortunately the service command on my qnap system is not located there: /usr/sbin/service

After a reboot file has disappeared:

[/etc/udev/rules.d] # ls -lisa total 4 37979 0 drwxr-xr-x 2 admin administrators 60 2022-01-28 01:12 ./ 37978 0 drwxr-xr-x 3 admin administrators 60 2022-01-28 01:12 ../ 37980 4 -rw-r--r-- 1 admin administrators 636 2022-01-28 01:12 65-drbd.rules [/etc/udev/rules.d] #

Sorry, my unix skills are only very basic

Florin Vlaicu

I've been through something similar. With kernel 5.5 (i think) the tvbutler device is supported by linux! (the instructions on the plex site are for the binary driver distributed with plex).
It seems this device needs to load 2 firmware files - the first is
http://trsqr.net/olli/linux/firmwares/it930x/dvb-usb-it9303-01.fw and the second is:

http://palosaari.fi/linux/v4l-dvb/firmware/Si2168/dvb-demod-si2168-02.fw

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

Hope this helps!

Hello Florin Vlaicu!

Thank you for your interesting post and sorry for my really late reply!

Unfortunately it doesn't work for me, I tried the following:

1. After I put the 2 files into /lib/firmware I plugged and unplugged the tuner a few times. There is no /dev/dvb

2. After a reboot the files where gone so I put them again into /lib/firmware. Same result as above

Do you have any further suggestions!

Saen Acro

Unplug and plug

 dmesg | egrep "firmware|dvb|frontend|usb"

and post result, after unplug message.

Florin Vlaicu

unless the kernel version is at least 5.5 the steps i provided won't work, you can check the version of your kernel by running:


uname -a

There is nothing with point to that anything want to load modules for tuner

Other thing is that you don't fallow steps to report messages
Interesting is that with happens after this message

This message can't be found on my system.

Thanks for the link to the example. Could you please give me a hint what I could find there?

As you pasted here, the kernel version is 4.14.24-qnap. It's less than 5.5 where this device is supported. You need to upgrade.

No changes from QTS 4.5 to QTS 5

> unless the kernel version is at least 5.5 the steps i provided won't work,...

Current kernel 5.10.60-qnap - 5.10 is newer than 5.5

TV Butler worked with old QTS 4 along with TV Mosaic due to its built-in support. TV Mosaic is now discontinued. Is there any chance to get my stick(s) working with TV Headend?

Is your logic on vacation?

after this message, plug device
and post result

To be more easy for you to orientate in time use


dmesg -T| egrep "firmware|dvb|frontend|usb"

Dear saen acro!

> Is your logic on vacation?
Because I'm new to this topic and only a basic unix user I'm very glad receiving suggestions from other users.

But may I ask you to stay friendly to other users which probably don't have your skill level.

Meaning after I unplugged the device and the 'removed' message I don't get any further messages on my system

Kernel 5.10 is a higher version number than the one with minimal requirement 5.5 so the DVB Stick should be theoretically supported

How can I make the following messages appear?

i am not familiar with the linux distro that comes with QNAPs, I would suggest you find out if there are any packages with drivers that you can install, here is a listing from raspberry pi which has the drivers for the device:

# lsmod|grep dvb dvb_usb_af9035 49152 0 dvb_usb_v2 53248 1 dvb_usb_af9035 dvb_core 155648 1 dvb_usb_v2 mc 73728 9 videodev,si2157,bcm2835_codec,dvb_usb_v2,videobuf2_v4l2,dvb_core,videobuf2_common,v4l2_mem2mem,bcm2835_isp

I think the kernel module that's needed is dvb_usb_af9035

Try running the command above before and after inserting the device, see if there's any change there.

TVButler is strange tuner from DVBLogic,
made for work only with their software.
to work as regular tuner need to be make some changes with are in first posts at topic
user#28152 need to write them on disk with need to be mounted as RW

I said I am not familiar with the QNAP linux distro.
I own the TVButler tuner :).

I recently made it work on my raspberrypi without the DVBLogic software (TVMosaic) using the steps I mentioned in this thread earlier: https://tvheadend.org/d/7998-dvb-c-usb-stick-recognized-dev-dvb-not-available-therefore-device-not-visible-in-tv-adapters?r=47653#message-47653

The steps you're mentioning are only useful if using the original software (TVMosaic), they won't work with TVHeadend.
