Description Mehmet Tekbaş 2011-02-27 15:23:08 UTC

I have an old Tv Card which is Lifeview's Flyvideo 98 analog TV cağture device. This card numbered as card=36 at bttv card list. I have video and sound from my TV card however kernel does not find my TV card's irda device at /proc/bus/input/devices . So I cant use my remote control.

Remote control receiver is connected directly to pci TV card.

Here is my /proc/bus/input/devices, other needed outputs are attached.

It looks like you have some stale modules:

Did the remote work before? Also could you try newer kernel, live 2.6.37 or 2.6.38-rc6?

Comment 6 Mehmet Tekbaş 2011-02-28 23:32:51 UTC

I installed and tried with 2.6.38-020638rc6-generic kernel version but system still cannot place remote control under /proc/bus/input/ .

Remote control works perfectly under windoz.

Comment 7 Mehmet Tekbaş 2011-03-10 08:51:59 UTC

Tried with Inca I-TV004 (bt878 analog card) and result didn't changed. IR device doesnt place under /dev/input/ . Can it be related to inputdev replacement of lirc_gpio?

Let's ask folks on linux-media mailing list...

There were no replacement. Both inputdev and lirc interfaces should be shown, if your device supports raw IR protocols.

Please post the dmesg logs with bttv ir_debug=1 option, for us to have a better idea about what's going on. Please also post the contents of the sysfs rc tree
with:
    $ tree /sys/rc/

Comment 10 Mehmet Tekbaş 2011-03-11 06:35:49 UTC

$ tree /sys/rc/
/sys/rc/ [error opening dir]

0 directories, 0 files
mehmet@mehmet-masaustu:~$ sudo tree /sys/rc/
/sys/rc/ [error opening dir]

0 directories, 0 files


Nothing changes with ir_debug=1 option.

Comment 11 Mauro Carvalho Chehab 2011-03-11 14:31:39 UTC

Please post the dmesg. The one you posted is useless, as it seems that you've mixed an upstream kernel with some out-of-tree driver compilation.

Please, get the latest upstream kernel (vanilla one, not the distro-patched), and send us the dmesg of it, with the ir_debug=1 enabled.
