Problem initializing device in gdm

["siddharth sharma rajput" <sidd_ait rediffmail com>]

    Hi Everybody,

         I am developing the facility of biometric login.
         I am using gdm for that.
         But when I tried to initialize the device in
         greeter code, it is not initializing the device.
         Device is biometric mouse.

         So Actually why I am denied the access to that device.
         Can anybody please suggest me a solution.

         Please reply soon.
