When an error occurs and it is necessary to reset, it cannot be reset without removing the USB cable even if the power is turned off. I want to know how to add a reset button.
The fix for the USB issue is to use a non-powered USB cable. I use a small bit of electrical tape to cover the 5v pin on the A end of the cable.
There is a video on it somewhere, but this is the easiest and cheapest solution.
Thank you Ac7ss,
I fixed the problem by your idea.

A little more violent than I would have done, but looks like it works.
