communication via usb

I would like to communicate with schneider premium plc on unity platform via usb since a com port is not available on laptop and the usb to com converter does not seem to work

I have tried it before without success. I ended up purchasing a unitelway USB connector for the connection.

2 cases here :
- either it's a 57-4 or 57-5 and the PLC ha a USB port so that you just use a standard cable. Thats' free and so simple.
- or it's a smaller one (57-1, 47-2, 57-3) and then you have to use the cble mentionned by Chrispen. No other choice .
