Lightberry USB doesn't work

Several years ago, I bought Lightberry for the first time with GPIO connections and everything worked fine. But last week, I had to order a new one since my previous one got broken.

What I did:

  • I downloaded the latest rasplex on a new SD card.
  • I enabled Hyperion support in settings
  • I already upgraded the firmware
  • I ran hypercon config tool
  • As stated on the support page, I modified the config file with the following code:
    “device”: {
    “colorOrder”: “bgr”,
    “rate”: 500000,
    “type”: “adalightapa102”,
    “name”: “MyPi”,
    “output”: “/dev/ttyACM0”
    },

But I still can’t get my Lightberry working. When starting up, the leds blink for a few seconds in several colours, so the connections are fine… I’m pretty out of ideas now…
