Need help getting started with Enttec OpenDMX USB

[nat...@lenovo-chrome.com]

Hello all,

I'm trying to get some basic functionality working with my lighting solution. I have a DMX-enabled light system connected through an Enttec OpenDMX USB bridge into an Arch Linux system.

I installed OLA, but I get the following when I run olad -l 4:

plugins/usbpro/WidgetDetectorThread.cpp:215: Found potential USB Serial device at /dev/ttyUSB0

So it seems like that's not working.

I also tried using the D2XX drivers from FTDI (which requires me to unload the usbserial module). I had reasonable success with the sample programs but couldn't get anything more advanced to work, so I decided to try the OLA route instead and that's what got me down this particular rabbit hole.

If anyone can help me find the quickest path to getting basic DMX functionality working, that would be MUCH appreciated.

Thanks!

Nathan

You need to either load the kernel module and disable the Enttec USB Pro plugin and the FTDIDMX plugin, or disable the Pro and Open plugins and use the FTDI one.
