ESP32 azure Iot Kit stopped recognized by usb COM port

[chrispal]

Hello everyone!
After a faulty firmware, that tried to accesS I2C from an ISR, my device stopped being recognized by the usb COM port that it is connected. When i plug the usb cable in, it is showing at the device manager, but after a second, it loses connection. What can i do to reverse the situation. I can upload any firmware right now.
Thanks!
