OBSIV: My quesetion to you is about the USB switch. When using a USB switch, it basically cuts off one device when you switch it. I.e. XBOX won't have access to the XIM 3 when I switch it over to PC. PC won't have access to it when I switch it to the XBOX. Does that mean I'm ogoing to get a "please reconnect your controller" notification when I switch to my PC? Perhaps someone else that's already using a USB switch can askwer that as well.
I would imagine that would happen, and then depending on how the XIM3 is interacting with the Xbox and the controller you might run into other issues. Guess that will be something to test out, seeing how the controller reacts to being connected/disconnected while in use.
Of course if the switch is before the adapter (mouse keyboard into switch, switch to XIM3 and computer), the adapter would likely retain it's connection because that's still hooked up and the controller is still plugged into the XIM3.
All speculation on my part just based on what I've seen.
