Serial port never shows up? Try activating Programing Mode

Hold the center button while turning the device off and then on to place Mezzz into Programing Mode. No leds will light up in this mode but the port will be visible.

Can't connect to serial port?

Make sure other programs aren't trying to use the port, including any IDE, browser, game engine, vj software etc.

Webtool not working?
