Setup ICOM 7300 and set up for FT8 - USB-D Issue
The first thing to do is to download this,

The 1.30 version of the USB driver is for Win 10, the 1.20 is for Win 7/8.
Install this then plug in the USB cable to have Windoze final the driver install.
This download and install is for the com port only, the USB Audio CODEC might already be
