Subject: [PATCH] Added temporary workaround hint
 "SDL_WINDOWS_DETECT_DEVICE_HOTPLUG"

Some devices with broken drivers hang when their name is queried, so added a workaround for applications that don't need input device details. The long term fix is to move the hotplug detection into a separate thread.
