digi tv kortti hauppauge hvr 900

[tes133]

olen yrittänyt netin eri ohjeiden avulla saada hvr 900 korttia toimimaan mutta en ole onnistunut niin ajattelin pyytää täältä apua. en ole käyttänyt ubuntua vielä paljoa. ongelma on että laitteisto tunnistaa korttini mutta en saa kuvaa aikaiseksi. en  tiedä onko ajurit asentuneet oikein. olen yrittänyt saada kortin toimimaan näillä ohjeilla.
sudo su
apt-get install mercurial linux-headers-$(uname -r) linux-source build-essential
cd /lib/firmware
wget http://konstantin.filtschew.de/v4l-firmware/firmware_v4.tgz
tar xvzf firmware_v4.tgz
hg clone http://mcentral.de/hg/~mrec/v4l-dvb-experimental
cd v4l-dvb-experimental
make
make install
reboot
sudo modprobe em2880-dvb
If on the next reboot, the card stops working the em2880-dvb module is not being loaded properly in Feisty. To fix this :
cd /etc/modprobe.d
sudo gedit dvbstick
then add this line to the new dvbstick file :
install em28xx /sbin/modprobe --ignore-install em28xx; /bin/sleep 2; /sbin/modprobe em2880-dvb

modprobe antaa tälläisen vastauksen

mikko@mikko-desktop:~$ sudo modprobe cx88-dvb

osaisko joku neuvoa mikä on pielessä. olis kiva saada toi digitv kortti toimimaan.

[tes133]

osaisiko joku auttaa.

[Anssi]

olen yrittänyt netin eri ohjeiden avulla saada hvr 900 korttia toimimaan mutta en ole onnistunut niin ajattelin pyytää täältä apua. en ole käyttänyt ubuntua vielä paljoa. ongelma on että laitteisto tunnistaa korttini mutta en saa kuvaa aikaiseksi. en  tiedä onko ajurit asentuneet oikein. olen yrittänyt saada kortin toimimaan näillä ohjeilla.
sudo su
apt-get install mercurial linux-headers-$(uname -r) linux-source build-essential
cd /lib/firmware
wget http://konstantin.filtschew.de/v4l-firmware/firmware_v4.tgz
tar xvzf firmware_v4.tgz
hg clone http://mcentral.de/hg/~mrec/v4l-dvb-experimental
cd v4l-dvb-experimental
make
make install
reboot

onko käytössä kenties hardy?
Ilmeisesti tuo  v4l-dvb-experimental ei tällä hetkellä toimi hardyssa, joten jos haluat hakea ongelmaan ratkaisua niin etsi sanoilla v4l-dvb-experimental hardy.
Itselläni ei ole korttia joka vaatisi tuota experimental pakettia, joten en voi testailla.

mutta jos käytät vanhempaa ubuntua niin sitten sen periaatteessa pitäisi toimia...
