Why would only one of my three USB ports not recognize my iPhone anymore? Is it missing a chromosome or something?

USB ports may get weak by time, mine was too, i have 4 usb ports and 1 one of them has malfunctioned, i dont know why, i just switch to another good usb port. It could also be caused by stucked iphone driver on certain usb port, just open device manager and delete that usb port. Next restart ur computer and it will be fine now.
