Routine Description:
Given a handle to a valid Hid Class Device Oject retrieve the preparsed data.
This routine will ``malloc'' the apropriately size buffer to hold this

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
retrieve information about a given device.
Return Value:
TRUE if successful.
