Hi All,
I'm running 2.6.38-ARCH and I installed lirc-utils with pacman. I have /dev/lirc0 and /dev/lirc1 created successfully after boot, so the kernel must have recognized my hardware correctly. I have two tuners in my system and both are the exact same card, TeVii S-460 with Conexant chipset, cx88.
I use only one remote at this time, it is /dev/lirc0, I believe. I had done as suggested on many threads:
echo lirc > /sys/class/rc/rc0/protocolsnow if I do:
cat /dev/lirc0I get continuous rubbish on the terminal, whether or not I press any key on my remote. If I press a key, the rubbish is increased as long as I keep pressing. This happens with lircd running and not running!. This makes me think that /dev/lirc0 is a raw device that hasn't yet kernel-treated.
Starting lircd and trying irw gives nothing at all. I tried many suggestions and read tons of articles, but the each time I end up with the same frustrating result.
Please find the relevant parts of config and log files:

lirc-utils 1:0.9.0-2What am I doing wrong? I'd appreciate any spotlight given on how to configure lirc correctly, as this box is acting as a mythtv backend/frontend, so the remote control is crucial.
In the journey of searching for the best distro ever, Arch Linux seems to be my final destination. No more fiddling with distros and comparing them, I also won't go back to Ubuntu any more, no more bloated installations for me, please.

cx88 cards spew junk in 2.6.38

After spending more time trying to get this issue solved, I'm all convinced now that the problem is more universal than it seemed to me at first. Many people are suffering the same behavior with the new kernel 2.6.38, let it be a vanilla kernel, or a distro patched one.
The major reason for all this mess to happen is that the IR subsystem is undergoing severe makeup operations and plastic surgery, they are replacing drivers and removing others. The bottom line is that the whole process didn't went as smooth as it should be, and it will take some time to iron the wrinkles and to let the new subsystem to heal completely. Until this happens, I guess one should opt for a USB receiver that is supported by lirc. I will look around for one, and I will post my results on how it did go with configuring it and getting it to work with my TeVii remote control.
However, thanks for help.
