I have two Arduino NANOs and one Arduino UNO. I try to connect the three boards but the serial port on the IDE doesn't appear to be enabled. When I open the Device Administrator, an error message appears... the warning triangle over the USB Serial Port (COM4)... and when I open the properties of the serial port to see what's the problem, the error message is: "This device cannot start. (Code 10)". I have already reinstalled the Arduino IDE, the Arduino drivers, the FDTI drivers... and nothing...
My laptop is running Microsoft Windows 10 Pro 64b - HP Laptop 15-bs1xx
Any clues on how to solve this?
