Hello,
this is my first time playing around with avrusb.

I'm trying to compile my project with it. Here is the output from a makefile:
(it's called usbrobot, but I'm not really making a robot)

I know it's probly something stoopid, but I've greped the files and can't even find usbFunctionSetup inside usbPoll...

You should implement usbFunctionSetup() in your code. See the examples which ship with avr-usb...
