When connected to a PC over a real 2-way i8042 port, the device identifies itself as: # grep '' /sys/bus/serio/devices/serio0/input/input2/id/* /sys/bus/serio/devices/serio0/input/input2/id/bustype:0011 /sys/bus/serio/devices/serio0/input/input2/id/product:0001 /sys/bus/serio/devices/serio0/input/input2/id/vendor:0001 /sys/bus/serio/devices/serio0/input/input2/id/version:ab41 # Unfortunatelly, it looks exactly the same as my standard AT keyboard. Can you imagine any other possible way of distinguishing them?
