How to check input device

[mike zheng <mail4mz@gmail.com>]

Hello,

It is the first time for me to use the input device. I have a keypad
driver registers a keypad the device as an input device in the kernel
2.6. The registration of the driver is OK, I can see the interrupt
whenever there is key pressed. How can I verify if it works fine?
Where can I check keycode value of the key pressed?

Thanks in advance,

Mike
