So I have the 2030 and when I connect it to a USB3 port (the blue one) on my computer the fn and the media keys, etc. don't work anymore, only the normal keys work, so I can't increase/decrease volume, I can't play/pause, I can't copy&paste, etc. I still can type and ctrl, alt and those modifiers work. Only the ones you need the fn key don't work.
When I move to a USB2 port then everything just works magically.
I am using it with Arch Linux and sadly I don't have a Windows computer with USB3 ports so I could test it there.
I am not sure that this is the right place to report bugs, if not, please point me to the bugtracker or something.
