I tried to activate my remote using the driver in
http://linuxtv.org/hg/~awalls/cx23885-ir.
According to the following dmesg output everything is loaded correctly and the
ir interface is registered as /dev/input/event5:

But there is no signal comming from input/event5, regardless of the tools trying
to access it (lircd, irw, mode2, inputlircd, plain cat, etc.). What else is
needed to activate the remote with this driver? If I enable debug messages by 
> modprobe cx25840 debug=2 ir_debug=2
> modprobe cx23885 debug=7

the dmesg/syslog is flooded with:

Any advice where to go from here, what to try?
Thank you.
