Thank you for the update and FB site recommendation. I’m beginning to think this might be an app problem and not hardware. Just to see I downloaded the light rider app which is pretty much the same app as mydmxgo and is from the same developer. I then tried to connect the interface to mydmxgo. I received the same waiting for device to become available message. Then I unplugged the mydmxgo interface and tried to use light rider to interface with my Airstream dmx bridge. I received the same message, waiting for device to become available. It’s very frustrating to spend $250 and wait an extra 3 weeks for delivery and then have the product not work. I’m seriously contemplating just returning it as this point. I hope a patch is found soon to fix the problems.
