serial port

You can not use a USB->Serial converter.
This type of converter requires a USB Host port (and a driver) because IS a USB Device.
You need a USB Host for using a USB Device.
Look for ftdi USB Host solutions...

If serial port is the PHYSICAL Serial port connection and you have that as the ONLY option for communication then you'll need to make an embedded USB host. It will get data from PC, and then send to the device connected to the other end. Not something that anyone will want unless extremely limited by the legacy system's constraints. You may be one of those

If it is that you are familiar with COM port communication programming and don't want to switch to USB (time constraints) then you can get an FTDI adaptor. You seem to be aware of that already.
