[linux-dvb] VisionPlus DVB + debian 2.6.10 + udev

[justin.smith@xelorsoftware.com.au]

Hi,

I am having trouble getting my VisionPlus VP-3021 DVB-TV card working
under Debian unstable with a Debian 2.6.10-1-386 kernel. The only module I
have compiled myself is the NVidia driver. I used a recent Debian
installer (Jan 1, 2005).

My goal is to get MythTV running, but right now, I can't even run scantv -
it returns:

v4l2: open /dev/video0: No such file or directory
v4l2: open /dev/video0: No such file or directory
v4l: open /dev/video0: No such file or directory
no grabber device available

So udev is not creating the correct /dev/video node/s. Does anyone know
why this is so?

The dvb devices are created OK, i.e.
/dev/dvb/adapter0/demux0
/dev/dvb/adapter0/dvr0
/dev/dvb/adapter0/frontend0
/dev/dvb/adapter0/net0

although, it appears from other postings that I should be seeing entries
for audio0, ca0, osd0, and video0 too. Is this true?


Here is the dmesg output:

Are any modules missing here?

The DVB card uses a Conexant Fusion 878A chip.

Note that I added the following to /etc/modules:
nvidia
dvb-bt8xx
dst

I haven't added any rules to /etc/udev/rules.d, I'm not sure what rules
and /sys entries udev should be using to create the /dev/video0 node
anyway.


Thanks in advance,
Justin.
