Hello,
I recently purchased an Arduino Nano (Geeetech/Iduino) however, I have been having the serial port "grayed out" issue with the IDE. I have tried installing the FTDI drivers and they say that the installation is successful (except when I use the executable version which gives me a "needs escalation error"). I have also tried older releases of the drivers. Regardless there are no ports listed under Device Manager. The PWR LED is solid where as the "L" LED is blinking at a slow rate (1 sec on 1 sec off). Is this possibly a faulty board?
Thank you for you time
Edit: I forgot to mention this though it is in the title, I am running windows 8.1
