[mythtv-users] Desperate: Help with ir-keytable and IguanaIR

[Tom Dexter]

Wow...I'm about to loose my mind here. As noted in a previous thread,
my old homebrew serial IR receiver appeared to have died. ir-keytable
worked with that for a very long time and now isn't getting any sign
of life at all from it.

I just bought an IguanaIR transceiver. I have the support enabled in
the kernel, as well as the NEC IR protocol:

CONFIG_IR_IGUANA=y
CONFIG_IR_NEC_DECODER=y

I know for a fact that my remote uses NEC (a Phillips TIVO34), as that
protocol worked when my serial IR was working.

EVERYTHING looks right here, and I'm just not getting any sign of life
out of this thing either. ANY suggestions are welcome. I'm about to
loose it here. This is what I have:

ir-keytable
Found /sys/class/rc/rc1/ (/dev/input/event5) with:
        Driver iguanair, table rc-empty
        Supported protocols: NEC RC-5 RC-6 JVC SONY SANYO RC-5-SZ
SHARP XMP other
        Enabled protocols: NEC
        Name: IguanaWorks USB IR Transceiver v
        bus: 3, vendor/product: 1781:0938, version: 0x0000
        Repeat delay = 500 ms, repeat period = 125 ms
Found /sys/class/rc/rc0/ (/dev/input/event0) with:
        Driver serial_ir, table rc-empty
        Supported protocols: NEC RC-5 RC-6 JVC SONY SANYO RC-5-SZ
SHARP XMP other
        Enabled protocols:
        Name: Serial IR type home-brew
        bus: 25, vendor/product: 0001:0001, version: 0x0100
        Repeat delay = 500 ms, repeat period = 125 ms

The first one is the iguana of course. As you see, NEC protocol is
enabled, which I did with:

echo nec > /sys/class/rc/rc1/protocols

I get nothing at all from "ir-keytables -t", and even from:

od -x /dev/input/event5

It can't be the remote itself, as I have two of them. No way did they
both crap out at once. I've even tried this on a completely different
Gentoo system from my frontend.

I even just tried recompiling my kernel without the serial_ir just to
make sure that wasn't somehow causing issues. Other than obviously
picking up different device and input paths, I get the same
behavior...basically nothing at all. Everything here just plain looks
right, much as it did when my serial receiver was working.

UPDATE: I also have and MCE USB receiver that I bought recently. That
simply had way too much lag which is why I didn't use it.
Interestingly, that DOES work with the NEC protocol with "ir-keytable
-t". Is it possible that the IguanaIR just doesn't work with the NEC
protocol?

Thanks in advance.
