[not solveable] Could not set up tvheadend MSI VOX USB2.0 TV BOX

Help and Support Raspberry Pi
1

Hi, new to osmc, I’m trying to make TV run.

[EDIT: I gave up. It seems not to be possible to make that device work. Rather keep away from it - or give me a hint. :wink:

https://de.msi.com/product/multimedia/VOX_USB2.0_TV_BOX.html#hero-overview]

First, I tried to install a VDR following: these instructions. But there was a compiling error, so I switched over to TVheadend.

First it successfully installed, but my MSI Vox USB adapter did not appear in the web interface. So I removed tvheadend, and tried to reinstall it - but that permanently fails - displaying a message “please report this error to the forum”. So I’m doing now.

Here are the logs:

Thanks a lot in advance,

According to your logs your Tv-Adapter is not recognized correct, you should create a file em2820.conf with the following content:
options em2820 card=5
save the file and move it to /etc/modprobe.d/
another thing is you must have the firmware file/s for your card in /lib/firmware.
Try to reinstall tvheadend with the following commands:
sudo apt-get purge armv7-tvheadend-app-osmc
sudo apt-get update
sudo apt-get install armv7-tvheadend-app-osmc
reboot

Thanks for the quick reply. Reinstalled tvheadend as advised. The DVB adapter seems not to register at startup, it seems to do after unplugging and reinserting.

But it still does not show up in the web interface under ip:9981

Here are the new logs:

Thank you so much!

Did you follow this?

5

Ufff - right, sorry. I didn’t pay attention for the firmware section.
But - how do I obtain the appropriate firmware? - Links I can find are something like 5 years old, likely not to be the best choice… )-:

6

So did you follow the first part of @franky384 suggestion?

Well how old is the device? I doubt it is newer than that, or?

7

Yes, I created a em2820.conf.
I bought the USB adapter last week. It came in the original package - but I’ve not idea, how old it really is.

In the respective folder with the right option? Did you rebooted? Because seems not successful

Maybe I created the em2820.conf in the wrong way? - Group and ownership was root before. I both to osmc - but still I cannot find the card in ip:9981.

ls -l /etc/modprobe.d/em2820.conf
-rw-r–r-- 1 osmc osmc 22 Nov 29 05:51 /etc/modprobe.d/em2820.conf

Recent logs are here:

Thank you very much for your patience!

owner/group should be root.
please post the output of:
dmesg | grep dvb
and:
lsusb
and:
lsmod
to see if your Stick is correctly recognized.
lsusb should give you an ID of your stick. Search google with this ID to find the correct firmware.
or look here for more hints: em28xx › Archiv › Wiki › ubuntuusers.de
or try
sudo apt-get install firmware-linux-nonfree

11

Right.

dmesg | grep dvb - does not give any answer.

This old article says that “eb1a:2820” has generic support.

12

but only if you install the nonfree linux firmware.
what’s the output of
dmesg | grep em28xx
or
sudo dmesg | grep em28xx

13

sudo dmesg | grep em28xx
[ 2035.117319] em28xx: New device @ 480 Mbps (eb1a:2820, interface 0, class 0)

You can try to install all firmware from here:

15

Thank you. But again, I seem to be too stupid. I cannot find any em2 file in that zip. Or what elso should I look for?

16

Simply copy all the files in the firmware directory to your /lib/firmware. It seems that some em28xx devices need the xc… , some need the it9135 firmware to work. The additional files don’t cause any harm. If you try another TV-Stick you have the needed firmware in place. This is only to test if it helps in any way.
dmesg | grep dvb must give some output, otherwise your stick is not recognized and i have no more ideas to test.
ps: have you tried to install the nonfree firmware:
sudo apt-get install firmware-linux-nonfree

17

All, or at least most of the OpenELEC/dvb-firmware files already were in my firmware directory.

Here I found that dmesg - this man has got a MSI VOS TV as as well:

em28xx-video.c: requesting em2880-dvb!
em28xx #0: V4L2 VBI device registered as /dev/vbi0
em28xx #0: V4L2 device registered as /dev/video0
em2880-dvb.c: DVB Init
Loading base firmware: xc3028_8MHz_init0.i2c.fw
Loading default dtv settings: xc3028_DTV8_2633.i2c.fw
xc3028-tuner.c: sending extra call for DVB-T

When looking for it, there seem to be plenty of xc3028 on my rasbpi:

find /lib/firmware/ -name xc3028
/lib/firmware/xc3028-v27.fw
/lib/firmware/xc3028-v24.fw
/lib/firmware/xc3028L-v36.fw

But another problem more and more comes to my mind:
Whenever I boot the rasbpi, no em28xx related messages occur in dmesg. I always unplug and replug the stick, then the messages come. Can the firmware only be loaded at boot time?
I consider, whether this is a power problem. But the dvb stick is at a powered hub, so should not cause problems.

I tried to remove my USB hard disk and power the DVB stick directly by the rasbpi. It seems not to work any better:

When trying to install firmware-linux-nonfree, I get these messages:

Removing /lib/firmware/v4l-cx25840.fw does not help.

Still a little out ouf clou…

Sorry, now i’m out of any ideas.

19

Well seems you got one of the most messy devices out there. To at least trying to get any close I think it is important that we figure out which exact device you have as it seems that you need to configure card and tuner option in the respective files. Maybe post some pictures of the product label.
Also one more question, what TV Signal (DVB-T, DVB-C, DVB-S) are you trying to record once this is working?

20

This (https://de.msi.com/product/multimedia/support/VOX_USB2.0_TV_BOX.html#down-driver&Win 2000) is the device. Bought it for 3€ incl. postage, but didn’t know that it is so old. And I learned that you rather use older devices than brand new ones with linux. Maybe was not a good idea in this case…

I’m going for DVB-C.

Thank you for your patience - greatly appreciated!
