Initialize a USBBackend.

Parameters:

  • id_vendor (int) – The USB vendor ID of the machine.

  • id_product (int) – The USB product ID of the machine.

  • device_address (int | None) – The USB device_address of the machine. If None, use the first device found. This is useful for machines that have no unique serial number, such as the Hamilton STAR.

  • serial_number (str | None) – The serial number of the machine. If None, use the first device found.

  • packet_read_timeout (int) – The timeout for reading packets from the machine in seconds.
