Dmitry-a-durnev, thank you for reporting this and helping make Ubuntu
better.

At your earliest convenience, could you please test the latest upstream
kernel available from the very top line at the top of the page from
http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D (the release
names are irrelevant for testing, and please do not test the daily
folder)? Install instructions are available at
https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow
additional upstream developers to examine the issue.

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, and Y are the first two numbers of the kernel version, and Z is
the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of
kernel-bug-exists-upstream.

Once testing of the latest upstream kernel is complete, please mark this
report's Status as Confirmed. Please let us know your results.

Thank you for your understanding.

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

Status in linux package in Ubuntu:
  Incomplete

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.
