Sometimes when I open the serial monitor (or run pio device monitor
), it shows error that says:
Disconnected (ClearCommError failed (OSError(22, 'The semaphore timeout period has expired.', None, 121)))
After that, my onboard notebook keyboard stops working and my USB mouse stops working as well. Therefore, I am forced to restart my PC by holding the power button. This started happening today and never happened for the past 3 months of using this notebook.
Any experience with this or any ideas how to fix this?
Thank you so much
