          dev_handle is the value returned by the open_device() method.
          The ep parameter is the bEndpointAddress field whose endpoint
          the data will be sent to. intf is the bInterfaceNumber field
          of the interface containing the endpoint. The data parameter
          is the data to be sent. It must be an instance of the array.array
          class. The timeout parameter specifies a time limit to the operation
          in miliseconds.
  
          The method returns the number of bytes written.
