--- Quote End --- It is off topic. You should start a new topic next time. In hardware, you can assign the ports usage, eg, ps2_0 for keyboard, ps2_1 for mouse. In software, you can query the devices to get device type. You will need to write serio driver for your PS/2 hardware. The kbd and mouse drivers will use it. linux-2.6.x/drivers/input/serio linux-2.6.x/Documents/input
