Zygmunt Krynicki, as per https://downloadcenter.intel.com/SearchResult.aspx?lang=&ProductID=3444&ProdId=3444 an update to your BIOS is available (0056). If you update to this following https://help.ubuntu.com/community/BiosUpdate does it change anything?  If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful. As well, you don't
have to create a new bug report. As well, you don't have to create a new
bug report.

For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.

Once the BIOS is updated, then please mark this report Status Confirmed.

Thank you for your understanding.

Title:
  USB 3.0 connection is unreliable + xHCI xhci_drop_endpoint called with
  disabled ep

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  On Utopic 3.16.0-9-generic x86_64 kernel:

  I'm using the Intel DQ77KB desktop board [1]. Apart from the board and
  some disks and memory the computer has no other hardware. The board
  has four usb 3.0 ports on the back. Using any of those ports, with my
  USB 3.0 hub, with my phone triggers a swarm of messages like this:

  xhci_hcd 0000:00:14.0: xHCI xhci_drop_endpoint called with disabled ep
  ffff880354156900

  If I connect the 3.0 hub via USB 2.0 hub instead, or use the 2.0 hub
  directly all of the problems go away.
