What I am trying do is connect to my network switch with a terminal emulation program via an Ethernet cable out of the back of the switch.

I know it works since I used it on an old win7 computer. But that computer is long gone. If someone can point me in a direction, it would be a big help. I have done all the net searches I can think of. We understand your concern. Click on View in the menu bar and select Show hidden devices. Was this reply helpful? Yes No. Sorry this didn't help. Thanks for your feedback. There is no com or lpt port line on this version.

It did show as described on my win7 machine but not on this version of device manager. I had "shown hidden devices" before, but to no avail, and I just double checked it again after reading your response. And thank you for the response. But so far I can still find nothing that associates usb devices to com ports on this machine. I had expanded the serial bus controller tree and checked properties of the three usb devices generic usb hub, usb host controller and usb root hub connected Still no com port information.
