No video0, /dev/dvb/adapter0 present

No video0, /dev/dvb/adapter0 present

[Cliffe]

Hello I would really appreciate some help.

I am trying to setup my TV HD tuner card and have encountered some problems.

In a nutshell:
I have /dev/dvb/adapter0
containing:
demux0  dvr0  frontend0  net0

but no /dev/video0

Some details:

Card: Leadtek DTV2000 DS Dual Tuner

Was not detected by OpenSuse 11.2
I tried building from the repo
(as described here: 
http://www.linuxtv.org/wiki/index.php/How_to_Obtain,_Build_and_Install_V4L-DVB_Device_Drivers)
but there were errors, so I grabbed from
http://linuxtv.org/hg/~anttip/af9015/
which was reported to work with the card

dmesg reported firmware missing, so I got dvb-usb-af9015.fw from
http://www.otit.fi/~crope/v4l-dvb/af9015/af9015_firmware_cutter/firmware_files/4.95.0/

Now it loads
(from dmesg):

But /dev/video0 does not exist which means none of the TV software works.

I don't know what to try next. Any help would be awesome.

Thanks,

Cliffe.

Cliffe,

Your card does not support analogue, hence there will be no /dev/videoN
node created.  You are most likely attempting to use analogue tv viewing
applications (i.e. xawtv v3.9x, tvtime, ...). Use applications for
digital tv instead (i.e. kaffiene....).

If you go back over the "How to Obtain, Build and Install V4L-DVB Device
Drivers" article, you will find links to two other articles

http://www.linuxtv.org/wiki/index.php/What_is_V4L_or_DVB%3F
http://www.linuxtv.org/wiki/index.php/Device_nodes_and_character_devices

which should provide you with fuller details.

Thanks! That helped get me back on track.

MythTV doesn't scan channels correctly (I thought it was related to
video0) but importing a channels.conf created using the scan program
works. So now I have a working MythTV setup!

Cheers,

Cliffe.

Hi Cliffe

Have you checked to see if there's a different report after a completely cold
(power plug out) boot, compared to a warm reboot?

I'm chasing what appears to me to be a similar problem, different card, same
chips (by the look of it) and I found the same report in my syslog:

Unknown device detected @ 1-00c0, device not supported.

I see you haven't had any responses here; did you get any further with this?

Symptoms in my system: got a dual tuner card (PEAK 221544AGPK PCI) which,
following warm boot, doesn't see the second tuner. Suspect firmware not being
loaded due to warm state. I'm documenting this at

http://www.slm.dnsdojo.net/content/tech/myth/index.php#begin_peak.html
