👋 Do you have an OpenDMX-compatible USB device connected?

MattIPv4 commented 1 year ago

You may want to pass ftdi_vendor_id and/or ftdi_product_id and/or ftdi_serial with specific values for you device to help locate it into OpenDMXController(). The code defaults to 0x0403 for the vendor id and 0x6001 for the product id:

Hi there, I had the same issue with Enttec OpenDMX USB on macOs, fixed by setting the LD_LIBRARY_PATH as mentioned here https://eblot.github.io/pyftdi/troubleshooting.html#error-no-backend-available

Cheers
