PS/2 was never design be hot pluged.
Alot of bios disable PS/2 I/O if no PS/2 device are plugin.
that mean u need to reboot you computer.
We play with the thung how to make PS/2 hot plug
1. We need write own chip driver for each chip.
2. No we need write a hw scanner that activate PS/2 within some time intervall
and disable it if no device are found.
Now to problem with this method is
1. some hardware can be damnges the mainboard when u
plugin the mouse or keyboard. it does not made if to high V or A are
beign send in.
if u only use one PS/2 port it is automatic made the second PS/2 hot
plugin depns on the mainboard bios or chip driver for the mainboard
in windows 3.x//NT 3.x/NT 4.x/95/98/ME/2000/XP/Vista/7
The question is does anyone want to write sepreate chipset driver for
each mainboard only support hotplugin for PS/2 and add this feature.
In linux many of the opensource chipdriver does support this feature
but not all.
