Hi,

I'm running Debian unstable and I'm trying to set up MythTV to use my
Twinhan VisionPlus DVB card. The card gets detected at boot time with
no problems, and the appropriate modules are loaded, but udev
(0.070-2) never creates any nodes in /dev for it.

The udev.rules file contains a match entry for 'KERNEL=="dvb*"', so I
added a catch-all entry that matches 'KERNEL=="*"', and outputs the
kernel device name to a file. Nowhere was there any dvb entries,
despite the dmesg output showing something about "dvb0"

Since my end goal is to get the card working under mythtv (which
expects the device to be under /dev/dvb/adapter*), and all the
documentation I see points to the fact that udev should magically
create all this, does anyone have any ideas as to how I can proceed?

Thanks,
-Grant
