Use FTDI USB serial ports - you can't go wrong with them. https://ftdichip.com/
I have, at the last count, used something like 200 of their FT232 device in one form or another on the shack PC. I know that, because device manager has registered up to COM200. Every time a new one is plugged in, a new COM port is set up.
