<![CDATA[USB Device not recognised]]>I was able to upload sketches to it if i dropped the upload speed to 115200 and i pressed the reset button when it was uploading but now windows (windows 10) isn't recognised the unit at all. I'm using the drivers that were recommended on the getting started section.

Wow! haha, just found the most weirdest solution,
not sure if the USB port in the M5 stack is wired properly,
If I turn the USB C cable around then it works, so it seems like the cable has to be a certain direction for it to work, I have even tested this with multiple cables all with the same result!, so if it's not working try rotating your cable!

this doesnt always work for me and i tried another cabel

I have just tried taking the bottom section off (the section with the battery in it) and it seems to be working fine now, as soon as I put that bottom section back on it doesn't work again, so strange....

Interesting, I never made that connection before.

(Code 43)

Is it the USB that is causing the issue?

My solution was the 0.1uf capacitor between RST and gnd and use a CH240 usb adapter instead of the inbuilt one.

I can plug it in and it works, but a little while later if I disconnect it and then reconnect it, this happens.
