So I was having problems getting the Nano to even show up in device manager until I saw a little exclamation mark beside the USB serial converter (under USB controllers branch) and updated that driver.
The Nano for some reason now shows up but only as COM3 with no description and it tells me that the latest drivers are installed.
However on the IDE the serial ports menu is still greyed out and when I try to upload to the COM3 port it gives me the same error as when the Nano didn't show up.
I know for a fact it is not the cable and it is a genuine FTDI chip. I feel like it's something to do with Windows 10 but I can't figure out what the issue is.
