I solved the same problem by putting a capacitor between Gnd and Gpio0. And i turned the USB-Plug many times around.
But now it starts as it should.

I took the backside off and plugged the capacitor in without soldering. (Maybe therefor i had to try several times)

Very strange and not funny for people with lesser frustration tolerance.

No, there was no COM-Port. As if it is not plugged or turned wrong around.
But as told, now it is ok. And i am glad it is. I like the M5s very much.

I still think, the capacitor solved it. But of course i am not sure.

I have a 'normal' M5 and a Fire. If i need the pins for testing and rapid development i do change the backside.
And i have bought some pure Pcb for the M5 which you can simply plug in instead of the backside.

Thanks for your answer.
I could connect after bridging GND with G0.
Before i tried to reverse USB plug many times without success.

For this reason (and because i have so many of them) wouldn´t it be nice to use Micro-USB? Most ESPs, Mobiles and many more use it and all of us have them for charging all the devices.

I managed to reach the fire by putting a little capacitor between Gnd and G0.
Sometimes. It is more astrological than technical.

As i read on another place, there is a failure in the board layout and one piece should be turned but my fingers are really too big to solder such small pieces.

Such a pity. I will send it back. In this way i cannot use it.

Hi there,
i just got a M5stack Fire. But if i connect it there is no connection with my Win Pc.
Another 'normal' M5 shows connection on COM9. And i use Arduino IDE without problems.
But the Fire doesnt connect.

What did i miss?
Thanks
