[pvrusb2] IR receiver does not see anything

[Siddhartha Jain]

I am running CetnOS 4.4 with 2.6.21.1. The hardware is Wintv-pvr-usb2
24xx. The in-tree kernel module works fine and this is what I see from
dmesg:

I compiled the ir-kbd-i2c module and I see this when I load it:
=====================

Looks good. I compiled lirc with the devinput driver and ran lircd
specifying devinput as the driver.
"/usr/local/lirc/sbin/lircd -H dev/input -d /dev/input/event4"
tail /var/log/lircd
-----
lircd: lircd(devinput) ready
------

Then I run, irw

May 13 01:59:48 linpvr lircd: initializing '/dev/input/event4'

Presseing different keys on the remote pointing it towards the
Wintv-pvr, I get nothing on the console.

So I tested the whole thing on a WinXP machine to verify if the remote
and the IR receiver do work. And they do.

Am I missing something here? Any help or pointers are welcome.

Thanks,
