My XPS13 running 14.04 always looses it's USB ports (it has only 2 USB 3.0 ports) after resume from suspend. Reconnecting USB devices doesn't help. But always help something like this:
echo -n "0000:00:14.0" | sudo tee /sys/bus/pci/drivers/xhci_hcd/unbind; echo -n "0000:00:14.0" | sudo tee /sys/bus/pci/drivers/xhci_hcd/bind
