When this object is read the current state is returned. idle(1) indicates that there is no copy in progess. complete(4) indicates that the last copy operation is completed. Setting the value to copy(1), will execute the operation (copy to or from USB stick). If the copy is successful this variable will return the state 'complete' else it will return 'failed'. Once the operation is completed, agUSBcopyFile should be set back to 'idle' state so others can issue the copy command via SNMP.
