Hi all!

I've poked around a bit on my freshly reinstalled system. To make things 
short, usbhidctl does not yield anything for the keyboard. I guess the 
reason is quite simple:

# kldload uhid
uhid0: <Apple Computer, Inc. IR Receiver, class 0/0, rev 2.00/0.16, addr 
2> on usbus5
uhid1: <Touchpad> on usbus5

So the keyboard isn't even recognized by uhid. See the attached file for 
some usbconfig device dumps, I can't make a lot of sense of it, but 
maybe someone can.

What would one need to do to still make usbhidaction (as an example) 
work with this device, so that the "additional keys" like the eject 
button and brightness/volume control etc. (mapped onto Fn + the F1-F12 
keys) would be reported?

Thanks!
