Computer Not Seeing Metro M4 Express

by ethaniel on Thu Feb 14, 2019 11:39 pm

Hi...
My Metro M4 express doesn't register on any computer; here's the story:
the board worked fine when I first got it, but all of a sudden my laptop (on Windows 10) started seeing it as an unknown USB device. I then plugged it into a desktop mac and it worked perfectly. However, because I wanted to use it on my laptop, I tried erasing the board, thinking that maybe then it would start registering as it should. As it was erasing, I accidentally pressed the reset button, and it looked like it stopped doing whatever it was doing, since the neopixel changed colors. After a little bit, I unplugged the board. Now, using the same cable that worked with the mac moments before, the M4 Express doesn't show up on any computer I have, except for my laptop, which still only sees it as an unknown USB device. Also, every time I plug it in the neopixel is a solid red. Is there any way I can get it working again?

What was the "erase" you were trying to do? Can you double click the reset button and get the METROM4BOOT folder to show up?

I followed the instructions to erase the board described here: https://learn.adafruit.com/welcome-to-c ... sues-19-20
I downloaded the erase file and dragged that into the METROM4BOOT folder, which immediately started erasing the board before I accidentally pressed the reset button again.
When I double click the reset button, my laptop still sees it as an unknown USB device and no other computer will see the Metro M4 at all.
