Query: This adapter works fine...

Got this adapter to use with a laptop that only had USB ports to communicate to some PLC's, which can be picky about communications. It works fine, and I found that, depending on which USB port I plugged the adapter into the adapter would show up as either comm4 or comm5, but if you think about it it makes sense for it to work that way, especially if you needed more than one adapter. If you want it to be comm4 all the time, for example, always plug it into the same usb port.........Curtis
