Arduino Nano Every & 27 WS2812B LEDs not quite working as expected

Correction, it's a mixed issue seemingly.

  • expensive USB C + micro USB adaptor on PC = works
  • expensive USB C + micro USB adaptor on Nintendo Switch Hub USB Port = works
  • expensive USB C + micro USB adaptor on Anker 4 slot USB Hub = works
  • any cable on Anker 10 slot USB Hub = flickers

Cheers again!
