EVIOCSKEYCODE support for HID (USB) went in in 2.6.22-rc1.

There is keyfuzz utility you can use to play with keymaps for a
particular device:

hi Dmitry,
I tried keyfuzz, but I'm not able to change sysrq key (I get an invalid
argument error).
I paste some log of my tries:

# uname -r
2.6.22

# for i in /dev/input/event*; do echo -e ">>>> $i:"; keyfuzz -i -d$i; done
 >>>> /dev/input/event0:
evdev driver version 1.0.0.
device name: PC Speaker
 >>>> /dev/input/event1:
evdev driver version 1.0.0.
device name: Mitsumi Electric Apple Extended USB Keyboard
 >>>> /dev/input/event2:
evdev driver version 1.0.0.
device name: Mitsumi Electric Apple Extended USB Keyboard
 >>>> /dev/input/event3:
evdev driver version 1.0.0.
device name: Microsoft Basic Optical Mouse

# echo "84 183" | keyfuzz -s -d/dev/input/event1
EVIOCGKEYCODE: Invalid argument

# echo "84 183" | keyfuzz -s -d/dev/input/event2
EVIOCGKEYCODE: Invalid argument

# echo "0x05d 0x0b7" | keyfuzz -s -d/dev/input/event2
EVIOCGKEYCODE: Invalid argument

(strace gives me no useful info)

What is 84? For SUB you map a "usage" to a keycode and regular key

                         ^^^ USB

usages start with 0x00070000...
