Chapter 3 Software Functionality

These modules talk to the hardware (for example via USB), and provide events

(keystrokes, mouse movements) to the input module.

B. Event handlers

These modules get events from input and pass them where needed via various

interfaces - keystrokes to the kernel, mouse movements via a simulated PS/2

interface to GPM and X and so on.

3.11.10.2Simple Usage

For the most usual configuration, with one USB mouse and one USB keyboard, you'll

have to load the following modules (or have them built in to the kernel):

input

mousedev

keybdev

usbcore

uhci_hcd or ohci_hcd or ehci_hcd

usbhid

After this, the USB keyboard will work straight away, and the USB mouse will be

available as a character device on major 13, minor 63:

crw-r--r-- 1 root root 13, 63 Mar 28 22:45

mice

This device has to be created.

The commands to create it by hand are:

cd /dev

mkdir input

mknod input/mice c 13 63

After that you have to point GPM (the textmode mouse cut&paste tool) and XFree to

this device to use it - GPM should be called like:

gpm -t ps2 -m /dev/input/mice

And in X:

Section "Pointer"

Protocol "ImPS/2"

Device "/dev/input/mice"

ZAxisMapping 4 5

EndSection

When you do all of the above, you can use your USB mouse and keyboard.
