Recently I buyed the above mentioned card. I fit in the card into my PC
which has an installed Linux Suse 9.0 distribution. In order to get the
card working I decided to download a 2.6.5 kernel. I built a kernel with
all necessary things (i2c support, bt848-driver, video4linux, .. refereing
to the kernel documentation .../Dokumentation/dvb/bt8xx.txt). My .config
file is attached to this mail. Now the problem is, that I can not receive
any data from the card. But let me explain the problem step by step.
After booting the kernel the card is visible via lspci:
lspci -v tells me:

The next step is including the driver modules into the kernel (see also /
Dokumentation/dvb/bt8xx.txt):
1. modprobe bttv i2c_hw=1 card=0x5c
After this step a look into /var/log/messages tells me:

3. modprobe cx24110

May 30 17:23:54 linux kernel: DVB: registering frontend 0:0
(Conexant CX24110 with CX24108 tuner, aka HM1221/HM1811).
After these steps I think I should be able to use the card. So I tried
out:
dvbstream -o -ps -f 12110 -p h -s 27500 2401 240
(normally the output is piped to xine or some other fontends)
Normally I expect that I should see the stream on stdout, means on my
console. But see what happens:
dvbstream -o -ps -f 12110 -p h -s 27500 2401 2402

I think that there is no signal available (see the last 2 lines,
FE_TIMEDOUT, Not able to lock the signal). I measured the dc-output of the
card, which should be 18 V. In fact there is 0,00000 Volt ! No LNB-Power
means no signal! I am sure that the installation of my satellite antenna
is correct. I normal digital satellite receiver has no problem and shows
maximum signal strength.
The /var/log/message file shows after dvbstream:

May 30 17:25:37 linux kernel: i2c_adapter i2c-0: master_xfer: with
2 msgs.
I'm not sure if i2c_adapter i2c-0: master_xfer: is correct here.
Do you have any ideas what could be wrong ? I do not know, if my card is
o.k. This is my first attempt to get them working. I have no direct
windows installation on my haarddisk (only wmware) so it is little bit
more diffucult for me at the moment to try them out on windows. I'm new to
the dvb card subject and I will be very happy for every hint.
I read a lot of things about dvb during the last time (www.vdrportal.de,
www.linuxtv.org, homepage of hubertus sandmann, .. ) but I have no
solution for my problem until know.
Thanks for your help in advance!
