Keyboard dead (logitech ultrax ps/2)

[tirrenia]

I have tried to run knoppix 3.6 from the cd.
My keyboard works on the boot: promt, so i can write boot options.
But when it´s in X the keyboard is dead.

I´ve tried NavynOS , another live cd dist and it´s the same there to.
The only diffrense is that navynOS starts i console (text) mode.
My keyboard is dead there also.

Is it the 2.6 kernel??

Any ideas??
