Hi

I'm trying to access the fifth DVB card with little success.
I've read some of the earlier stuff (what I found) and I do
have dvfs enabled and can access /dev/dvb/adapter0-3 but it seems to
fail with adapter4.

Kernel is 2.6.6

Here is what I have

ls -l /dev/dvb
total 0
drwxr-xr-x 1 root root 0 Jan 1 1970 adapter0/
drwxr-xr-x 1 root root 0 Jan 1 1970 adapter1/
drwxr-xr-x 1 root root 0 Jan 1 1970 adapter2/
drwxr-xr-x 1 root root 0 Jan 1 1970 adapter3/
drwxr-xr-x 1 root root 0 Jan 1 1970 adapter4/

# ls -l /dev/dvb/adapter4
total 0
crw------- 1 root root 250, 1 Jan 1 1970 audio0
crw------- 1 root root 250, 6 Jan 1 1970 ca0
crw------- 1 root root 250, 4 Jan 1 1970 demux0
crw------- 1 root root 250, 5 Jan 1 1970 dvr0
crw------- 1 root root 250, 3 Jan 1 1970 frontend0
crw------- 1 root root 250, 7 Jan 1 1970 net0
crw------- 1 root root 250, 8 Jan 1 1970 osd0
crw------- 1 root root 250, 0 Jan 1 1970 video0

This is what I get when I try to access the fifth card

This what my syslog tells me when I boot

So it seems like it should be ok ? Or not ?

Kind regards
