So I bought the h110 mobo and it has two normal usb port and 2 3.0 usb ports but as my 2 rear normal usb ports are occupied by mouse and keyboard and now I wanna attach my 10 years old xbox 360 controller but there's no normal usb port vacant at rear so should I just plug it into usb 3 and call it the day or usb 3 ain't backward compatible
