Andy, I have also found that Windows will reassign USB ports if anything is plugged in or unplugged. My solution was to set the default sound system to the onboard system and use USB for the ham devices, such as the SignaLink USB. The problem is especially troublesome when I plug my WebCam microphone in and out. If you use Skype, it will also "grab" your microphone. Sorry, that I don't have a foolproof solution for you., but offer you comfort in misery! ;-)
