No, IR is not the problem here.

IR is the only part that works.

Looks like saa716x_tbs_dvb module is is crashing.

Why? Well, that I can not tell.

I'm afraid that at this point I can not help.

srx srx

Can you post output of:

uname -a

And can you tell, did you run:
./v4l/tbs-x86.sh
or

./v4l/tbs-x86_64.sh

Maybe you did compile wrong version... well... not sure that is possible. But it's a thought.

Arshvinder Singh Sehmi

Please confirm me one thing I am using this card and it is working perfectly under windows media center 8.1

Also, I have not connected extra power cable that is shipped with this card.

Do, I need to connect that power cable to power the card under ubuntu

If it works under windows, then I can not see why it should not run under linux.
Extra power cable should be used, specially if you use more than one input. Otherwise you can burn your card and/or motherboard. PCIe can not deliver enough power.

I doubt that absence of extra power cable will make driver crash. But you can try if it makes a difference. It's easy to add that cable. If your PSU has PCIe graphic card power cable, then it's even easier, it's the same thing.

I'm using extra power cable. But I'm using all four inputs too. I do not even want to try what happens without it.
I'm running Ubuntu 12.04 LTS 64bit on AMD Phenom X2 and 2GB ram on some cheap Gigabyte motherboard.
Kernel is 3.8.0-29-generic

I'm using this driver: tbs-linux-drivers_v130927.zip

And it works, no problems.

Arshvinder Singh Sehmi

Right now I am using only 1 input of card.

and when i use the following command

lspci -v

it yields, it means that ubuntu detects my card. But TvheadEnd donot

Right now I am not sure if my PSU has PCI-e graphics card power cable. Please suggest me what to do if I don't have PIC-e power cable.

Can I use any power cable that is comming out of PCI-e to power this card?

srx srx

No, that means that kernel sees PCIe device and reads the information that PCIe card provides.

It does not mean that it recognizes it and driver is working. Every card provides similar information without driver.

if you run:


dmesg | grep -i dvb

you should get output like this:

and

ls -l /dev/dvb

should list four adapters:

if /dev/dvb is empty then driver is not working.
if dmesg | grep -i dvb shows you errors like this, then your dirver is crashing:

OK thats fine.

Please confirm me can I use any power cable comming out of PSU to power this card?

I ran the command and I got the following -

root@HP6040in:~/tbs/linux-tbs-drivers# ls -l /dev/dvb
total 0

drwxr-xr-x 2 root root 100 Jan 12 00:49 adapter0

So, the issue is that driver is crashing?

srx srx

PCIe power cable is 2x3 connector with only black and yellow wires.

http://www.playtool.com/pages/psuconnectors/pcie6.jpg

If you have adapter, then use any cable that fits to adapter. Just make sure that the cables go in easy and the right way. It is possible to connect it wrong way if you use force.

Arshvinder Singh Sehmi

What about the cable that is supplied with the card?

Its one end is having similiar to the black connector shown in the above screen, and other end fits into the PSU connecter.

That means you have ONE adapter listed. TBS6985 is quad tuner card and you must have FOUR adapters listed.

Until that command does not show at least four adapters there is no point to even look at tvheadend.

Do you have any other DVB cards in your computer? I wonder what that adapter0 is if your driver does not work.

Arshvinder Singh Sehmi

Yes, I ahve checked the cable that is provided with the card. It is same as shown in figure.

Its one 2x3 end connecter goes into card and other goes to PSU Connecter. Is it?

Then you connect it to the card and use one or more cables from psu that fit. Any cable is ok.
All cables provide the same: two blacks in the middle are ground, yellow is +12v and red is +5v

I have NVidia GeForce 9500 GT in my PC at PCIE

And also I have connected LNB feed to only one TBS Adapter at the back

srx srx

Just use the provided cable. Connect it to the card. And use any available power cables from your PSU that will fit.

If your PSU does not have any free cables, that fit the adapter, then you have a problem.

I would use the cable regardless of how many inputs I use, just to be sure I do not burn anything.
You do not need all 3 cables connected I guess. If you can connect even one, it would be good.

Arshvinder Singh Sehmi

I am not getting what you meant in this line

You do not need all 3 cables connected I guess. If you can connect even one, it would be good.

Shall the read 3 in the above line as 2? (Are you talking about PCIe power cable?)

Also, I am not getting why PCI-e is a multiheaded cable, the end point that goes into card is one - that is other, why there are 2 ends at the other end?

So these 2 ends needs to be connected into PSU, or only 1 is enough?

srx srx

The cable that came with my card was like this:

http://cdn.overclock.net/b/b9/b95b0618_molex-to-pci-express-2.jpeg

But my cable has 3 connectors, not 2. I can't even find a picture with 3 connectors from internet. Maybe I got the only one :)

Maybe you only have two...
Either way... the connector that is black on the picture goes to your DVB card and the other can be connected to any available power cable from PSU.
If you do not have enough power cables available to connect them all, then just one or two will work too.

One is enough for now.

Why it's "multiheaded"? Because one wire can only carry limited amount of current. One molex connector (4-pin connector) has only one +12v wire. But PCIe connector has 3 +12v wires.

If you connect only one wire then it can not carry enough current for high end video cards. Actually high end cards have 2 PCIe connectors.

I'm not 100% sure about it, but one PCIe connector should be able to carry about 150W or so, that makes about 50W per wire. In our case we do not need 150W maybe 50W or even less. So only one cable should be enough.

PCIe x1 port on the motherboard can supply 10W for sure. It could be that it can provide up to 25W but I need to check it.
10W will not be enough, that I'm sure of.
