=== IR support in newer kernels ===
You have an howto in french here for debian :
Newer kernels require the creation of '''/etc/modprobe.d/cx23885.conf''' containing <code>options cx23885 enable_885_ir=1</code> for IR support.
http://wiki.debian-facile.org/manuel:installation:dvb:dvbs2:dvbsky
After a reboot '''/sys/class/rcX''' should show up (X starting at 0 with no other IR devices around).

== Warning ==

The driver seems to have some configuration issues:
http://code.mythtv.org/trac/ticket/10830

Also reported problem with openelec

The card needs a power supply other than the one provided by the PCIe, so there is a plug on the card. It can not work if not connected.

If configured properly, card works really well under MythTV 0.25.2 & Unicable.

IR support in newer kernels

Newer kernels require the creation of /etc/modprobe.d/cx23885.conf containing options cx23885 enable_885_ir=1 for IR support. After a reboot /sys/class/rcX should show up (X starting at 0 with no other IR devices around).
