I am trying to setup 2.4GHz Airmouse too. According to your guide, I installed empcd and base-devel. And it seems that the Airmouse remote identified. But only volumeup and down are working.
So, I need to find Key name of mouse button to describe in empcd.conf. But I dont know.
How can I get the Keyname?
I posted a guide on my website. It's in German. You may want to use google translator.
