A little bit more info: dmesg reveals:
Linux video capture interface: v1.00
bttv: driver version 0.9.16 loaded
bttv: using 8 buffers with 2080k (520 pages) each for capture
bt878: AUDIO driver version 0.0.0 loaded
bt878: Bt878 AUDIO function found (0).
bt878_probe: card id=[0x11822],[ Twinhan VisionPlus DVB ] has DVB functions.
bt878(0): Bt878 (rev 17) at 00:09.1, irq: 10, latency: 32, memory: 0xec800000
Is this card being supported? Or did I end up with an unsupported card
version?
Why do I not get any message that it is loading the dvb_bt8xx driver?
Thank you and best regards,
Z.

I am trying to get a Twinhan 20310 (budget DVB-C/CI) working under
Linux-2.6.17.5 on a Gentoo platform (udev).

After compiling and installing my kernel, I downloaded mercure +
v4l-dvb sources, and compiled / installed those as well; they do link
properly against my 2.6.17.5 kernel.
Now if I run 'make insmod' in the v4l-dvb directory, all the drivers
get loaded, but no '/dev/dvb/' directory pops up. However, a directory
'/dev/v4l' does show up, with video0 device inside. 'make rmmod'
nicely removes the v4l-directory as expected.
In /etc/udev/ruled.d/50-udev.rules, there is a line:
SUBSYSTEM=="dvb", PROGRAM="/etc/udev/scripts/dvb.sh %k", NAME="%c"
And the script /etc/udev/scripts/dvb.sh contains:
#!/bin/sh -e
echo $1 | sed -e
's#^dvb\([0-9]\)\.\([^0-9]*\)\([0-9]\)#dvb/adapter\1/\2\3#'
exit 0
It seems that all is in accordance with:
http://www.linuxtv.org/cgi-bin/viewcvs.cgi/dvb-kernel/linux/Documentation/dvb/udev.txt?rev=1.1&view=markup.
Checking udev-output (after enabling udev-debugging) reveals that the
udev-rule for SUBSYSTEM="dvb*" is not matching: the output in the log
files says: "udev_rules_get_run: rule applied, 'dvb-bt8xx' is ignored".
I am somewhat stuck at this point. It seems to me that everything is
going fine, except that udev cannot match the dvb-rule when the driver
is being loaded.... And I do not understand why this rule does not
match. How can I get more debugging info?
Or perhaps this is a well-known problem, with an easy fix? ;)
Thank you and best regards,
Z.
