I'd recommend trying an RS-233 port, if at all possible, or can you try another USB to Serial adapter?
I have a catchall "troubleshooting USB to Serial Adapter" section in K3 Utility Help that covers almost everything I've ever heard. USB to serial adapters do fail sometimes, as do USB ports, and not all failing devices announce themselves as inoperative. If you have more than one USB hub on your computer, try a different one. Look to the Windows Device Manager for the COM port assignment as it will very likely be different if you move the KUSB from hub to hub.

I'm using the USB/SERIAL adapter from Elecraft. The USB ports are working on the computer. Any ideas of what I can check? Thanks.
