Hi,
I have an old bt878 based analog card. It's 'Hauppauge WinTV Radio'
model 44914,
rev C121.
I'm trying to workout support for this shipped remote control. I have
tried to add
following lines to bttv-cards.c and bttv-input.c, but that gived
really bad results
(dmesg output is in attachment).

So I guess that's not going to work. I have read in
wiki that Hauppauge cards needs ir-kbd-i2c, so I tried with that too, but
then similar error like previous happens when I try 'modprobe ir-kbd-i2c
debug=1
hauppauge=1' as well as just 'modprobe ir-kbd-i2c'.
Can I have a little pointer what to do?
Regards,
Samuel

Did some investigation, maybe this can help to clarify some things. Still
didn't get any response in dmesg from remote.

If I comment above line segfault does not occur. Tried the remote under
windows, and is working properly.
