Title:
  USB 3.0 hub has no power when USB storage device is plugged

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  lsb_release -rd

  Description:	Ubuntu 15.10
  Release:	15.10

  linux-image-4.2.0-17-generic

  When I plug USB 3.0 storage device(Transcend TS32GJF780 USB 3.0 32 Gb
  flash drive) into one of USB 3.0 ports in USB hub (DELL U2713HM
  monitor) and hub is connected to USB 3.0 port on my MB - no USB device
  is detected. lsusb shows no device is connected to hub ports:

  lsusb -t
  /:  Bus 06.Port 1: Dev 1, Class=root_hub, Driver=ehci-pci/2p, 480M
      |__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/8p, 480M
          |__ Port 2: Dev 3, If 0, Class=Human Interface Device, Driver=usbhid, 1.5M
          |__ Port 6: Dev 4, If 0, Class=Video, Driver=uvcvideo, 480M
          |__ Port 6: Dev 4, If 1, Class=Video, Driver=uvcvideo, 480M
          |__ Port 6: Dev 4, If 2, Class=Audio, Driver=snd-usb-audio, 480M
          |__ Port 6: Dev 4, If 3, Class=Audio, Driver=snd-usb-audio, 480M
  /:  Bus 05.Port 1: Dev 1, Class=root_hub, Driver=ehci-pci/2p, 480M
      |__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/6p, 480M
          |__ Port 3: Dev 3, If 0, Class=Human Interface Device, Driver=usbhid, 1.5M
  /:  Bus 04.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/2p, 5000M
      |__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/4p, 5000M
  /:  Bus 03.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/2p, 480M
      |__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/4p, 480M
  /:  Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/2p, 5000M
  /:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/2p, 480M

  Expected: hub device on Bus 04/Port1 has storage device listed.

  Workaround: if I check if power is supplied to the USB 3.0 hub device,
  I see:

  cat /sys/bus/usb/devices/usb4/4-1/power/control
  auto

  Then if I manually turn power on:

  echo on >/sys/bus/usb/devices/usb4/4-1/power/control

  USB 3.0 device appears and works. 
  This problem is not reproducible if the same USB hub is attached to USB 2.0 port, so it is likely to be USB XHCI driver problem.
