I do turn on CONFIG_VT, if I don't I will not be able to pass compiling the keyboard.c and some other stuffs. Because I did not turn on INPUT_EVDEV, so I did not create the device node before. However, I just gave it a quick try by turning on INPUT_EVDEV and create the device nodes; and actually I saw response on input/event0!! Thanks! Now I have some questions: 1. I have CONFIG_VT on, so why ttyN is not connected to the device? I saw console.o and tty_io.o, etc. What may be wrong or did I miss doing some things that I should do? 2. In the application, how can I know which input/event# the usb keyboard connects to? 3. Is there some reference documents about how to read things from input/event# ? I mean such as how to read key event?
