TBS 5928 usb Ras Pi 4 TVheadend

Michael Berg

Hi guys,

Years ago I have bought a TBS 5928 usb adapter.
I remember it was nightmare to get it working.
Now years later I was wondering if I can still use the device in the latest TVH build with Kernel 5.10.17-v7+ ?
Anyone still got a TBS 5928 ?
Would anyone please be so kind to help out ?
Thank you very much.

TBS Are generally quite good at supporting linux,but you need to install and build drivers from media_build:


cd /usr/src
git clone https://github.com/tbsdtv/media_build.git
git clone --depth=1 https://github.com/tbsdtv/linux_media.git -b latest ./media
cd media_build
make dir DIR=../media
make allyesconfig
make -j4
sudo make install

curl -L http://www.tbsdtv.com/download/document/linux/tbs-tuner-firmwares_v1.0.tar.bz2 | tar -jxvf - -C /lib/firmware/

reboot

Thanks for your reply, but I keep getting this ?

make[2]: Leaving directory '/usr/src/media_build/linux'
./scripts/make_kconfig.pl /lib/modules/5.10.17-v7+/build /lib/modules/5.10.17-v7+/build 1
Preparing to compile for kernel version 5.10.17
You appear to have loadable modules turned off in your kernel. You can
not compile the v4l-dvb drivers, as modules, and use them with a kernel

that has modules disabled.

If you want to compile these drivers into your kernel, you should
use 'make kernel-links' to link the source for these drivers into
your kernel tree. Then configure and compile the kernel.
make[1]:* [Makefile:376: allyesconfig] Error 255

I have run make kernel-links, rebooted and compiled again, but same message.
Thanks

What OS is this? Debian on RPi? what does uname -a say?

Thanks for getting back.

Still got an issue here.

You need to fix this before proceeding:

Thanks again for your help here,

Just an update. It turned out that the SD card on my pi has corrupted.

I have build the drivers on a physical PC X64.

However if I try to scan the whole system freezes ?

No issues with another DVBSKY USB card on the same system.

Looks like a driver / firmware issue.

Any more suggestions ?
Thanks

Anders Gustafsson

OK. FWIW I run my TVHeadend on a separate Linux box. I am also moving away from USB adapters because of the problems I have had. I have now installed a TVS PCI card.

I had to build those drivers from media_build so I installed a test machine with the same kernel version and tested there, then moved to the "production" server.

??No issues with another DVBSKY USB card on the same system.??

Is this the same type of card as the TBS?

??However if I try to scan the whole system freezes??

You mean dvb_scan?

Anything interesting in dmesg?

Michael Berg

Is this the same type of card as the TBS?

No total different make has also got a CI but not using it.

With the TBS card I get this on nearly ever transponder.

2023-02-03 10:36:18.238 mpegts: 10853.44H in Hotbird - scan no data, failed

2023-02-03 10:36:18.238 subscription: 00EB: "scan" unsubscribing

1/2 way through everything is freezing up and I have to disconnect the power from the TBS card and kill/restart TVH.

The DVBSKY card can scan all of them.

Anders Gustafsson

Most likely a driver issue. Does it need a special FW? Is that downloaded to lib/firmware.

Try with just this adapter. Reboot, then start tvheadend, then look at dmesg.

Michael Berg

I did this
curl -L http://www.tbsdtv.com/download/document/linux/tbs-tuner-firmwares_v1.0.tar.bz2 | tar -jxvf - -C /lib/firmware/

I can't find any other or newer firmware?

What I would do at this point is to ask in the TBS support forums.

When it hangs, does it hang hard or is the keyboard still responsive?

Michael Berg

I'd love to but my account doesn't seem to be active once I registered lol.

I am in an ssh session but I guess the keyboard would still work.

Anyway, thanks for your time here, I'll try the TBS forum and if they can't help the TBS card is going in the bin.

Looking at getting a similar card to the DVKSKY at least they work out of the box.

Thanks again.

Anders Gustafsson

OK. If you can, try top and see what is eating resources.

I have had nothing but grief with USB adapters, especially the cheap chinese clones where two may look identical, but have different chipsets.
