Changing input device

Hi all,

so i have an acer desktop with built in ir
and an hauppauge pvr150 with USB SMK ir receiver/blaster

i can only get the built in ir receiver to work…

i can see the hauppauge ir with lsusb
Bus 002 Device 005: ID 0609:0334 SMK Manufacturing, Inc.

but only the built in acer ir receiver is shows up in
cat /proc/bus/input/devices

and of course only the built in ir is mapped in

usb-Acer_IR_Receiver-event-ir → …/event3

if i cat /dev/lirc0
it read the signal from the remote but has no effect on the system

also /dev/input/ir is mapped to /dev/input/event3
how can i change this to /dev/lir0
