@Samux6146,
check the back of the part that is inserted into the USB socket. The contacts on the back - where you can solder on a socket - is covered with the white paint, the same one used to mark things on the board. Over time - and especially when you have tin leftovers on the USB contacts that make the board thicker and create more pressure - this paint wears off and exposed contacts short with the usb socket ground / finger springs that hold the plug/board in the socket. That could be the issue that Espruino Pico's signal are not coming thru anymore.
