Multiple USB to DMX interface support?

Comienza en el punto de entrada OpenDMXController mostrado en el ejemplo y sigue cómo se seleccionan y gestionan las interfaces USB. Reproduce la configuración con dos dongles FT232R/libusb-win32; se considera terminado cuando las fixtures asignadas a cada dongle pueden controlarse simultáneamente.

Hi Matt! I‘m currently trying to use this library for a lighting project. I use USB to DMX interface cables with FT232R chip. I used "zadig" to flash the driver of interface to libusb-win32 and successfully dim the light on PC using Python! Thankyou :)

But I found when I plug two dongles in my PC, it seems that it can only control one of them. Luminaires of the other cable won't work.
Does this library support multiple interface to work simultaneously?

I am not a programmer. If I question something wrong please forgive me. And here's my code:

# Create controller
dmx = Controller()

# Load fixture from JSON
dmx.json.load_config('LabLight.json')

# Define a global fade time
fade_time = 5000

# DMA Value Mapping Percentage
def percent_to_dmx_value(percent):
    return int((255 * percent) / 100)

# clear
dmx.clear_all_effects()

for brightness_percent in range(5, 101, 5):
    dmx_value = percent_to_dmx_value(brightness_percent)
    # Dimming
    for f in dmx.get_fixtures_by_name_include('DownLight_1Y'):       # Y for Yellow light, W for White light
        f.dim(dmx_value, fade_time)
    for f in dmx.get_fixtures_by_name_include('DownLight_1W'):
        f.dim(dmx_value, fade_time)
    for f in dmx.get_fixtures_by_name_include('DownLight_2Y'):
        f.dim(dmx_value, fade_time)
    for f in dmx.get_fixtures_by_name_include('DownLight_2W'):
        f.dim(dmx_value, fade_time)
    # rest of downlights

    time.sleep(3)

# Manual Close
dmx.sleep_till_enter()
dmx.close()

And the json:

    {
        "type": "Generic.Dimmer",
        "args": [],
        "name": "DownLight_1Y",
        "start_channel": 1
    },
    {
        "type": "Generic.Dimmer",
        "args": [],
        "name": "DownLight_1W",
        "start_channel": 2
    },
    {
        "type": "Generic.Dimmer",
        "args": [],
        "name": "DownLight_2Y",
        "start_channel": 3
    },
    {
        "type": "Generic.Dimmer",
        "args": [],
        "name": "DownLight_2W",
        "start_channel": 4
    },
    {
        "type": "Generic.Dimmer",
        "args": [],
        "name": "DownLight_3Y",
        "start_channel": 5
    },
    {
        "type": "Generic.Dimmer",
        "args": [],
        "name": "DownLight_3W",
        "start_channel": 6
    }
]```

There're more but it's just for example.

For instance Downlight1-3 connect dongle_1, and 3_6 connect dongle_2.
