I have stm32f4-discovery board where I uploaded an appropriate firmware of espruino. When I attached it to PC the COM port was found. I installed the VCP drivers from espruino website. COM port was recognized as COM14. When I run IDE and click the "Attach" button it says there no ports found. What the problem is?
