        The given `instr_address` defines the instrument-address.
        It can be either
         - An empty string or None (meaning no address)
         - IP-Address in digits and dots format (e.g. '192.168.0.170')
         - TCPIP NI-VISA format: 'TCPIP::<IP-Address>::<PortNo>::SOCKET'
           (for example: 'TCPIP:192.168.0.170::5025::SOCKET')
         - USB NI-VISA short-format: 'USB::<VendorId>::<ProductId>::INSTR
           (for example: 'USB::0x168b::0x2184::INSTR')
         - USB NI-VISA long-format: 'USB::<VendorId>::<ProductId>::<SerialNo>::INSTR
           (for example: 'USB::0x168b::0x2184::0000214991::INSTR')

        In order to findout the USB-Address, use `usbtmc.usbtmc.list_devices()`.
        If for example it returns: `[<DEVICE ID 168b:2184 on Bus 001 Address 002>]`
        then the USB-Address is: 'USB::0x168b::0x2184::INSTR'.

        In case of multiple devices, the serial-number can be added too.
        For example: 'USB::0x168b::0x2184::0000214991::INSTR'

        Note: If either `instr_addr` is None or `tcp_timeout` is None,
        then the the previous value of the relevant argument is used.

        :param instr_addr: the instrument's address.
        :param tcp_timeout: TCP-Socket time-out (in seconds)
