[solved] Re: no key strokes from remote console when no keyboard attached

[Frank Hempel <red_socks@gmx.de>]

just for completeness:

to have the keyboard driver enabled regardless whether a keyboard is 
attached or not, one solution is to return Zero in the atkbd_probe() 
function of the atkbd input module if the atkbd->connect() function was 
called for the serio Kbd port.


so far, frank.
