DVB-T card no /dev/dvb/ node udev

[walrus_55]

i have a dvico fusion HDTV-DVB-t plus card and i have compiled support for the cs88xx chipset in the kernel and it get recognised proberly:

this is some relevent output from dmesg

so as you can see it is recognised corectly, my problem is that mythtv and the scan function from linux-dvb-* pagake both look for dvb cards in the /dev/dvb/ node but i dont have that all i get is /dev/v4l/video0,

is there something i need to do to point this card to the right nodes?

both look for dvb cards in the /dev/dvb/ node but i dont have that all i get is /dev/v4l/video0,

If you can't reconfigure mythtv or linux-dvb to look at /dev/v41/video0 then you can just create a symbolic link from /dev/dvb to /dev/v41/video0 you can do it like this:

ln -s /dev/v41/video0 /dev/dvb

Then you should be able to rerun the configuration utility to properly detect the card.

Thanks for the idea but mythtv needs i think it is /dev/dvb/frontend0 and all i get in the /dev/v4l dir are video0 and vbi0,

[variant]

well then symlink the real device to whatever it is that mythtv needs (/dev/dvb/frontend0)

I believe the device API for /dev/dvb/xxx devices are totally different from the /video and /v4l devices, so just symlinking won't work.

The correct devices need to be constructed for the dvb drivers - am currently looking into this myself !

However the basic point are
1) ensure you have a 2.6 kernel
2) check you have the correct drivers for your hardware - and they are getting loaded
3) if the /dev/dvb devices are not getting created - Google further !! Maybe you need to add some more udev rules.

I have looked in /usr/src/redhat/BUILD/kernel-2.6.x/Documentation/dvb text files ...
