You don't need any others. If you use these IOCTLs, the device event
bitmaps are automatically updated to add the new keys to the keyboard.

You can use evtest (attached). It's often found in the joystick RPMs.
It's also in the linuxconsole.sf.net CVS repository.  On recent kernels
it'll show the scancodes as well as the generated keycodes.

Linux input event extending tool exist?

[Aivils]

Hi Vojtech?

	Exist right now tool which one allow to use ioctl() like
EVIOCGKEYCODE , EVIOCSKEYCODE
an so define new scan-keycodes for unknow "Pluto-Pepino-Paperino"
keyboards which keys sometimes will not generate input event
on /dev/input/eventXX

	How to debug keyboard, when showkeys keep silence?

Vojtech, are you aware that this doesn't work well with 32-bit apps on 
x86-64 kernels? The ioctls don't work (no compat definitions), and 
struct input_event is 24 bytes instead of 16.

Yes, I'm aware of that, and I don't have a solution for it yet, since
adding compat ioctls is easy, but using the right input_event size is
next to impossible.

The problem is with the difference in size of struct timeval.

Yes, I do. It's a bug, and will be a hard one to solve. The ioclt()s are
easy, but the event size difference is pretty nasty.
