Eco button as mpd skip button

We have this cute usb Eco Button lying around, which is meant to put your computer in sleep mode in order to save energy. It would be nice if we could use it as an mpd next button.

Button gets recognized as shown in dmesg:

[ 1856.485618] hid-generic 0003:0C50:1010.0003: hiddev0,hidraw0: 
USB HID v1.10 Device [One small click One big change One small click One big change] 
on usb-0000:00:1d.1-2/input0

After reading [1] I was hoping this would be easy, but it seems this particular button does not generate keypresses in X.

So over to [2], and more info on [3]. Got an error similar to [4]. After editing hid.c it compiles.

And it does stuff too \o/. This command:

sudo ./hid_mapper --learn --manufacturer 'One small click One big change' \

--product 'One small click One big change' --map Outputs:

So it seems that after the button is pressed, a sequence of two events is repeated X times (seems to depend on how long button is pressed). I'm having trouble feeding it the correct map file. With a map file like this:

0219018f921100a80280240836200888:KEY_UP

or this:

0219018f921100a8:KEY_DOWN
0280240836200888:KEY_UP

This command:

sudo ./hid_mapper --manufacturer 'One small click One big change' \

--product 'One small click One big change' --map 'eco.map' spits out this error:
