Hello,

the wskbd mux device can't deal with keyboards using different  
scancode sets in event mode. When asked for its keyboard type it  
returns garbage in such a case ( think Apple laptop with built-in ADB  
keyboard and USB numberpad ) and events have no indication on which  
scancode set they're using.
To deal with it we could add translation tables which map native  
scancodes to USB scancodes to all keyboard drivers so they can pretend  
to be USB keyboards in event mode and avoid this problem. Otherwise  
we'd have to add an indication which scancode set is in use to struct  
wsevent which would require userland changes.
As a bonus we could also filter out things like the volume control  
keys found on various Sun and Apple keyboards and have them send PMF  
events even in event mode. Maybe even make it a runtime option.

This is fairly trivial and only requires a little legwork, probably  
too easy but it has to be done at some point. It also requires access  
to a fairly diverse array of hardware to test it. At least a macppc  
box with an ADB keyboard is absolutely essential since this is by far  
the most common offender, a pre-USB Sun would be nice to have and for  
reference something with a PS/2 keyboard too.

I'd mentor it, martin@ said he's interested as well.

have fun
Michael
