[linux-dvb] Re: Nova-T USB - Nothing in /dev/dvb

Hi

DVB drivers in 2.6.8.1 does not yet have udev support so in there you 
will always need to
create /dev/dvb entries with the MAKEDEV-DVB.sh. I do not know why it 
does not work for you,
could it be that udev is somehow refreshing /dev directory structure and 
entries created with
MAKEDEV-DVB.sh gets removed.

I am also using udev with Mandrake linux but instead of using dvb 
drivers from the kernel
I have downloaded and compiled them from the linuxtv cvs. These drivers 
in the linux-tv cvs
does have udev support. If you want to get automatic dev-entry support 
use drivers from
the linux-tv org cvs and make following udev configurations. 
(Mandrakesoft cooker have added
them already to their udev-rpm.)

1) copy attached 06-dvb.rules to /etc/udev/rules.d/06-dvb.rules
2) copy attached attached dvb.sh to /etc/udev/scripts/dvb.sh
3) add following entry into /etc/udev/permissions.d/00-udev.permissions
   #----------------------
   # dvb drivers
   dvb/*:$local:video:0660
