dunno,  never had a keyboard not work with a ps2 adapter.

wow! i guess you do haev 6 usb controllers.  to hide them just add them all to 
sys-usb except for 12.0    what pc/mobo do you have out of curiosity?

I dunno what all that salt stuff means i'm a total noob.  But I do know if you 
want to use a usb keyboard,  you gonna have problems.
