Hi support team,

I am trying to get a TBS 6920 running on YaVDR 0.5.0 (Ubunutu 12.04 with kernel 3.2.0-27-generic). I took the current driver package V130127 and installed it as described in the README file. Everything went fine, no errors were reported. After rebooting the machine the cx23885 module is not loaded automatically. After loding it manually (modprobe cx23885), there is still no /dev/dvb* device available. What can be the problem in my case? I really don't know, what do do now. Thanks in advance!

Hi TheMaggot.
As I see in your lspci output, you haven't got a TBS6920, this is a TBS6922.
TBS6920 use cx23885 module, but TBS6922 use SAA7160.

I'm not sure why your card isn't recognized, but can you post complete output of dmesg?

Best regards.

Hi SergioDanielG,

that's crazy - I was really sure, that I bought a 6920. Is the driver the same? Or should I build another one?

My full dmesg output is not accepted as text, because it is too long. It was also not possible to upload it as attachment, because the forum does not accept files without extension or extension .log or .txt. How can i attach the file properly?

Best regards,
Marco

Hi Marco.
Try to zip your file and attach it.

And see my pci oputput

Hi SergioDanielG,

thank you for the fast reply. You can find the dmesg log attached as zip.

OK, problem solved

I have downloaded the 6922 driver and installed it like described in the README. The card is now recognized and the modules are loaded properly:

@SergioDanielG: Thanks again for your help!

Congratulation! And now, enjoy your TBS6922.
