Malaise, the next step is to fully reverse commit bisect from kernel
3.13 to 3.17.8 in order to identify the last bad commit, followed
immediately by the first good one. Once this commit has been identified,
then it may be reviewed as a candidate for backporting into your
release. Could you please do this following
https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F
?

Please note, finding adjacent kernel versions is not fully commit
bisecting.

Thank you for your understanding.

Title:
  Lenovo B5970 USB peripherals are not detected

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Randomly (around twice any 3 reboot), Linux does not detect the USB peripherals of the laptop.
  When everything is ok, lsusb:
  Bus 001 Device 002: ID 8087:8000 Intel Corp.
  Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
  Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
  Bus 002 Device 004: ID 0cf3:3004 Atheros Communications, Inc.
  Bus 002 Device 003: ID 0bda:579c Realtek Semiconductor Corp.
  Bus 002 Device 002: ID 1d57:32da Xenta 2.4GHz Receiver (Keyboard and Mouse)
  Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

  When it fails:
  Bus 001 Device 002: ID 8087:8000 Intel Corp.
  Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

  Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

  I will complete the report with dmesg,  lspci -vnvn, lsusb -vv when it
  fails.
