I use a laptop. (Windows 7 64 bit)
Also, I don't think I explained my problem correctly. My software is old, and only can use com ports to communicate. But my external devices are much newer, and use usb ports to communicate. (not com ports) I'm trying to make the devices look like they are using a com port to communicate, and not a usb port. I don't need an adapter, as the devices already use the usb ports. I'm just trying to make them show up as a com port. I don't know how to write software, so I'm trying to find a program that will allow me to make the usb port show up as a com port.
