M4 Express AirLift serial connection problem

by nim5 on Fri Nov 26, 2021 6:57 pm

Hi all!
Earlier this week I bought an Adafruit Metro M4 AirLift, Connected it to the PC and ran some codes using Arduino IDE on it successfully. but suddenly I started to get Couldn't find a Board on the selected port error.

The Port item in Arduino IDE's Tools menu is greyed out, and I don't see the device by running lsusb(on Linux) or in the device manager(on Win10) - it used to show as /dev/ttyACM0 on my Linux box.

I tried Loopback test with no luck.

Do you know what could be the cause? Is there any way I can fix it?
