Why would I want to use the “Switch selected device to ID1 for play” option?. What does that mean?
Windows keeps track of each of your controller devices using “Device IDs”, which range from ID1 to ID15. Most newer games will work no matter which ID your controller is on; however, some older games will only respond to the device assigned to ID1. This feature may not work properly if you do not have administrative rights on your computer.
