Hi Mauro, All

Would it be an alternative to let lirc do the mapping and just let the
driver pass the codes of the remote to the event port.

For most devices, this is already allowed, via the standard
EVIOCGKEYCODE/EVIOCSKEYCODE ioctl. 

There's a small application showing how to change the keycodes. It is called
"keytable", and it is avalable at v4l2-apps/util directory at our development
tree:
	http://linuxtv.org/hg/v4l-dvb

Yet, there are some DVB-only devices that use a different way to support event
interface that doesn't allow userspace to replace the IR tables. I've looked on
the dvb-usb code recently. While a patch for it is not trivial, it shouldn't be
that hard to change it to support the key GET/SET ioctls, but a patch for it
requires some care, since it will touch on several different places and drivers.

I'll probably try to address this later.

Cheers,
Mauro
