Routine Description:

   This routine will ``malloc'' the apropriately size buffer to hold this
   preparsed data.  It is up to the caller to then free that data at the
   caller's conveniance.

Arguments:
   HidDeviceObject a handle to a HidDeviceObject.  The client can obtain this
                   handle via a create file on a string name of a Hid device.
                   This string name can be obtained using standard PnP calls.
   PreparsedData   an opaque data used by other functions in this library to
                   retreive information about a given device.

Return Value:
   TRUE if successful.

   ConfigurationLength that is ``sizeof (HIDD_CONFIGURATION)'' using this
