I investigated the problem and found out two things: 1) The keyboard works correctly in grub2 2) More important: the keyboard works correctly in Linux IF I use the simple HIDBP driver (usbkbd) instead of the regular one. So now I'm using usbkbd as a workaround, but this way I cannot use advanced hid devices like joysticks (becouse they are incompatible with HIDBP drivers). Is there any other information I can provide which could be useful?
