Public bug reported:
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
I had the same problem with 3.13.0-46
