Arduino Nano Windows USB Port
I bet that you have plugged in your Arduino Nano and don't understand why it does not appear as a USB port.
It is stupid!
If you check your Device Manager you will find that something has been detected (maybe FT32R USB UART) ... BUT... it has not found a driver for it.
No fear... you can download the driver for that, install it, then install the driver for the USB port.
Here is the video that I found which explains it all:
