New to the input layer

[Franz S. <Fra...@la...>]

Hi,

I'm currently working on the integration of PMac ADB into the input layer. 
I use the 2.2.16 USB backport for my work and most stuff works well 
already. But I have some generic implementation questions now:

- who will assign a BUS_ADB number? I used 0x17 for now
- why is there no mixer device /dev/input/events similar to 
/dev/input/mice? Should I implement such a device?
- only 32 event devices, looks a bit short sighted?
- the [sg]etkeycode ioctls are not implemented yet, anyone working on this? 
If not, I'll probably give it a shot
- it seems an ioctl to set the key bitmap is needed, cause I have an USB 
keyboard here which reports 0x65 keys, when in reality it has 0x67 :-(
- what key entry in input.h relates to the "Fn" key found on notebooks?

Thanks,
Franz.
