Arduino suddenly stopped being recognized. It is not listed in /dev and dmesg -w shows no activity at all when un/plugged.

I'm on Fedora 33. The Arduino is MKR-Zero. The cable is ok - other devices work well. I tried it on windows machine - same result - in Arduino IDE the option for port is greyed out.

Very weird thing happened before this issue- when I was trying to flash sketch, audio connected to docking station switched to speakers in laptop and keyboard + mouse connected to the docking station powered down (back light on keyboard went off and could not be turned on) however the Num lock light was on.

I'm afraid that I burned the Arduino - how do I verify if that is the case. The "ON" LED is lit up when plugged in

Ok, I have no idea what the hell is this, but when I double-press the reset button (while connected/powered on ofc) it works again. This can be seemingly cycled - press once and it goes wrong, press twice and it's ok again... round and round. Seems more like some retarded "feature"
