EPOC's gyro as a first person camera

Hey, guys! I have a really big problem with my unreal game developing… This is because this project is for my final thesis which I present in 5 days!!
I use a first person template and everything works well except my gyroscope input. I am using the gyroscope on the EPOC headset and all I want to do is to set it as the camera controller… In fact, my computer recognises that gyroscope and I can even set it up as a mouse. Although, when I try to use it inside the engine it seems to not work at all… I have tried creating a new controller but it does not work as well… To make it simple, all I want to do is to replace the default x-y mouse movement that controls the camera and assign this function to the gyro…

Any help would be appreciated!! Thank you in advance!
